Installed Module Options: - Advanced Management - Cable Modem - HIP - Docsis 3.0 CM Annex A+B - BERT, Throughput, RFC2544, Loopback - TOA - Docsis 8X4. Includes Carrying Case & Accessories As Listed Above!

Analog and digital carriers are very different in terms of signal content and power distribution and thus require the advanced SLM techniques supported in the CX350. In analog mode, video and audio levels, V/A, Gated C/N, Adjacent channels, gated CSO, CSO/CTB, and HUM are measured. In digital mode, average power, MER, Pre-BER, Post-BER, Error seconds, and constellation diagram are displayed.

User programmable location thresholds and test point compensation are useful utilities enabling fast, simple and automated testing of carrier signals. Digital pictures do not show signal impairment until it is too late because the margin between acceptable quality and failure is quite small. A valuable tool to help detect the presence of noise, phase jitter, interference, gain compression, laser clipping and ingress, all of which impact overall signal quality and thus reduces Modulation Error Ratio (MER). The Advanced Digital Analysis option has added in depth analysis of a QAM carrier with Phase Jitter, Group Delay, Symbol rate error, Frequency error, Maximum Amplitude Change, HUM, C/I, C/N, and Frequency response measurements. The built-in equalizer does a great job of improving MER of a QAM signal, but it is also important for technicians to know how hard the system is working to ensure adequate margin for system degradation. The adaptive equalizer in the CX350 can be turned off to make troubleshooting marginal amplifiers, ingress, CPD and related impairments easier. Within seconds, all analog and digital channels at a service location are measured. Signal parameters including channel number, channel name, frequency, modulation type and power levels are measured. Signal degradation or tilt can be easily pinpointed using on-screen markers and the zoom mode.

Noise impulses can suddenly disrupt a digital carrier but it is difficult to detect without monitoring the carrier over a period time. The histogram feature records level, MER, Pre-BER, Post-BER, and Error seconds on per second time bucket for up to 60 minutes.

The results are shown in graphical format that allows easy correlation of measured parameters down to one-second resolution. Tilt measurements identify distortion over the frequency range allowing technicians to apply correct equalization or compensation to the HFC network. Up to eight analog signals and digital carriers including DOCSIS channels can be predefined on a channel table and selected to perform the tilt measurement. The measurement can be performed between the lowest and highest channel or any user selectable channel by tapping the applicable bar on screen. The CX350 applies advanced signal processing techniques to detect opens, short circuits, splices, taps, water ingress and other elusive impedance mismatches on coaxial cables up to distances of 2 km (6,000 ft) with ± 1% accuracy.

The cable under test is scanned within seconds, allowing the user to view the full run and to identify faults quickly. Novice TDR users will appreciate the pre-set gain and pulse width feature which automatically adjust the vertical position of the trace for each range setting. All major operating and setting parameters can be easily accessed using only 4 tabs located at the bottom of the screen. Experienced technicians will benefit from selectable impedance settings and adjustable Velocity Propagation (VP) factors to perform various tests on different cables.

Up to 16 analog and 16 digitals are checked against preset location thresholds. The feature is particularly useful to verify and turn up service at new installations or after service is restored, Pass and Fail conditions are color coded for easy interpretation and test results are clearly displayed. This automatic test procedure adds consistency to the final service qualification. The CX350 can store up to 20 channel tables each of with can be pre-programmed with channels to be used for installation check.

Throughout a CATV system, power is distributed in the form of QAM, QPSK, TV and FM carriers, pilot tones, test signals, and noise. Impulse noise and narrowband ingress are detrimental because they distort or obliterate desired signals in the network. DOCSIS 2.0/3.0 standards include recommendations and limits for downstream and upstream RF performance.

Forward Error Correction (FEC) and deep interleaving techniques help protect IP data against radio frequency (RF) noise impairments; however network performance is often impaired by interference. Cable modems transmitting on frequencies with high levels of noise are susceptible to packet loss and uncorrectable FEC errors are indicative of degraded upstream performance and poor data throughput.

The return path is more susceptible to RF impairments because the frequency spectrum is heavily used for Hum and Citizen Band radio transmissions. Interference is not only limited to RF transmissions; Impulse noise generated by electric motors, switches, lightning strikes, high voltage power lines, vehicle ignitions, or household electrical appliances at the subscriber premise are particularly damaging to data transmissions where short bursts of interference can seriously reduce data throughput. The return path is also very vulnerable to a phenomenon known as Noise funneling. The summation of all unwanted noise (Gaussian, ingress and impulse noise) coming from both subscribers and the cable plant itself affects the return transmission system and needs to be monitored. Ingress and impulse noise can cause signal clipping when upstream fiber amplifier inputs are presented with excessive power levels.

As more carriers are added to the return path using channel bonding, composite power to the laser will increase. Common Path Intermodulation Distortion (CPID/CPIM). Spurious signals appearing in the upstream composed of distortion products of the downstream signals.

Lower frequency components are passed through the diplex filter and amplified by the return amplifier. Common Path Distortions are intermittent by nature and are directly related to poor connections, corrosion, kinks and radial cracks in the cable.

Interference originating outside the CATV system (co-channel and ingress) or generated within the system (inter-mod, hum and cross modulation) occur frequently in the forward path. DOCSIS 3.0/Euro-DOCSIS 3.0 Modem Emulation. Equipped with a CableLabs® certified cable modem based on latest generation DOCSIS 3.0 technology, the CX350 enables technicians to perform dual band RF connection tests, without having to carry a separate test modem on service calls. At a glance, the technician is able to view a summary of the ranging and registration process, check AES and Baseline Privacy (BPI+) encryption status and identify which connection parameters have passed or failed.

The cable modem offers data transmission speeds up to 220 Mbps (downstream) and 100 Mbps (upstream) using four-channel bonding technology. A range of downstream and upstream link connection parameters including frequency, power, modulation, symbol rates and signal margins are evaluated and displayed. DOCSIS 3.0 provides several enhancements, most notably channel bonding giving cable operators a flexible way to increase bandwidth to customers. Upstream speeds in particular have come under a lot of pressure due to a sharp increase in user generated content such as video and photo uploads, driven by the proliferation of social and networking sites.

Checking RF Levels - Significant consideration must be given to the cumulative RF power loading that is realized with upstream channel bonding. Four upstream DOCSIS channels transmitting simultaneously can result in a large contiguous channel loading. To avoid excess power hitting the return path fiber-optic transmitter and to reduce the possibility of laser clipping, the power levels of each channel can be carefully monitored in the link measurement tab. IPv6 Support and Network Server Verification. Once successful upranging is complete, the DOCSIS 3.0 modem registers with the Cable Modem Termination System (CMTS) and checks for an IPv6 address before looking for an IPv4 address.

IP addresses from the network servers (DHCP, TFTP, TOD, and DNS) are discovered and clearly displayed. Additional DOCSIS 3.0 Modem Features. Enhanced Security Advanced Encryption Standard (AES) support. Pass-Through testing modem emulation to verify high bandwidth data transfer between PC and Network.

Evaluate the bandwidth and noise performance characteristics of the reverse path with a choice of CW, QPSK, 16 QAM, 64 QAM and 128 QAM modulation types using industry standard symbol rates. Transmitting a known reference signal between 5-65 MHz (Annex A) or 5-42 MHz (Annex B) into the reverse path at a user defined power level and modulation, allows a technician to evaluate phase and amplitude distortions resulting from any misalignment present in the network. Injected reference signals can be used to determine the headroom in the reverse path and to identify laser clipping resulting from signal overload. The USG function fitted with Forward Error Correction (FEC) capability, is compatible with the Return Path analysis options found on VeEX CX180+, CX180R, CX350 and CX380 CATV test sets including selected 3rd party CATV QAM analyzers.

Depending on the companion analyzer used, Digital channel power, MER (equalized and unequalized), Pre/Post FEC, EVM, Phase Jitter, Hum, Group Delay and Symbol rate errors can all be evaluated. These tests are invaluable to characterize the in-channel flatness, in-channel group delay, and adaptive equalizer operation. The CX350 incorporates a sweep transmitter (USG) capable of generating sweep tones over a 5 MHz to 65 MHz frequency range with 125 kHz resolution, and amplitude levels ranging from 0 to 58 dBmV with 1 dB resolution. When paired with a companion CX380 handheld unit or a CX180R rack mount Ingress system located in the Headend, the entire return path frequency spectrum can be precisely characterized for DOCSIS 3.0 communications. Protection Guard Bands can be pre-configured to prevent test tones interfering with active DOCSIS transmissions.

The sweep system communicates the user defined sweep tables and measured test data over the Internet, freeing up valuable downstream bandwidth typically used by conventional telemetry systems found in competitor systems. Return path troubleshooting and testing is simplified when the CX350 is equipped with the Remote View option. Utilizing a wired (10/100Base-T or DOCSIS) or wireless (3G UMTS or 802.11 WiFi) Internet connection, a technician operating the unit in the field is able to view real time measurements being performed by the companion CX380 or CX180R located in an upstream Node or Headend itself. Developed specifically for dual ended test applications, evaluating MER, BER and Constellation and other advanced measurements like group delay and frequency response is extremely fast and convenient. In addition to sweep, real-time return path ingress measurements performed in the Headend by the CX380 or CX180R spectrum analyzer can also be viewed, thus making it a truly unique solution for upstream testing and characterization. Single copper (RJ45) and optical test ports (SFP) support 100% wire speed traffic generation and reception for 10/100/1000Base-T, 1000Base-SX, 1000Base-LX or 1000Base-ZX full-duplex networks at all packet sizes. Automated test suite performs throughput, latency, frame loss, and back-to-back frame tests, and checks all industry recommended frame sizes (including two user defined frame sizes) up to full line rate. The test can be performed with a far end test partner in loopback mode (symmetrical traffic) or peer-topeer mode (asymmetrical traffic). User defined test thresholds ensure accurate SLA assurance/verification while an advanced SLA mode generates background streams to closely approximate actual live traffic conditions.

Layer 1, 2, 3, and Layer 4 BER tests are supported. PRBS, stress or user defined test patterns simulate various conditions. Service disruption measurements including CRC error checking are performed.

BER testing is possible using a physical loop at the far end (Layer 1), or using a second test unit or intelligent loopback device in Smart Loop or in Peer-to-Peer mode. VLAN stacking (Q-in-Q) is supported for Metro and Carrier Ethernet applications. Up to three tags makes provision for carrier/service provider assigned VLANs, while retaining the VLAN of customer traffic.

Testing with multiple streams enables service providers to simulate and qualify a variety of applications and perform Ethernet QoS measurements. Up to eight individual traffic streams can be configured with independent VLAN stacking (802.1ad Q-in-Q), VLAN ID (802.1Q), VLAN Priority (802.1p), ToS and DSCP settings. Frame delay (PDV) and inter frame delay variation (IPDV) measurements based on RFC3393 recommendations are performed on test traffic during BER or throughput tests when unit is equipped with the Jitter software option. Four modes are available for looping test traffic.

Layer 1 - incoming traffic is looped back unaltered. Layer 2 - incoming unicast traffic is looped back with MAC source/destination addresses swapped. Layer 3 same as layer 2 with both MAC and IP addresses swapped. Layer 4 same as Layer 3, with UDP/TCP ports swapped. Todays cable operator network infrastructure, which combines a 40G/10G backbone with DOCSIS 3.0 over HFC, has strongly positioned MSOs to offer business class Ethernet based services to small and medium businesses.

Key service offerings include guaranteed data, hosted voice, online backup and security, and other cloud based services. Using its built-in Ethernet test traffic engine, the CX350 can generate traffic over the DOCSIS test port to verify bi-directional, end-to-end DOCSIS throughtput rates with a far-end Ethernet test device. Verification is done from the Customer Premise to the Headend CMTS. In Ethernet over DOCSIS mode, the CX350 emulates the Cable Modem and simulates the customers Ethernet traffic, up to maximum DOCSIS 3.0 throughput rates.

This unique capability is ideal for MSOs to verify their Metro and Carrier Ethernet Service offerings. Actual Cable Modem CPE verification can be performed by connecting the CX350s Ethernet test port to the Cable Modems Ethernet port and generate test traffic to the farend Ethernet test device connected behind the CMTS. The Asymmetric RFC2544 test suite offers an automated verification of throughput rates.

The Throughput application enables for deeper troubleshooting and verification with differentiation of traffic flow types (Constant, Ramp, and Burst) and different frame size configurations. From the Customer Premise, test directly at the RF interface or through the real Cable Modems Ethernet interface. At the CATV Headend office, connect a MPX100 or any other VeEX Ethernet test set behind the CMTS. Here the MPX functions as a Responder, with only an IP address needed to be configured on the test port. The CX350 functions as the Controller via the RF or Ethernet interface, running the RFC2544 Asymmetric test suite.

Encountering a variety of complex daily tasks is common in todays network environment, so technicians need a tester that is easy to configure and which doesnt require extensive product training beforehand. Taking this into account, the test interface, signal structure, and test pattern setup boxes are structured logically so the user can quickly and efficiently configure the unit via an intuitive graphical menu. A detailed summary screen clearly displays the signal status and Pass/Fail criteria for each major performance parameter alerting the user to any problems. Color LEDs provide information about the current status of the instruments receiver - indicators toggle from green to red when an alarm conditions occur.

Summary indicators are coupled to the high level Alarm/Error LEDs which can be hidden or viewed depending on operator preference. The unit incorporates CSU and NIU emulation which helps to isolate problematic T1 circuits.

Loopback status, Code and Frame errors including Level measurements are presented in an easy to read table. Dedicated function buttons are immediately accessible to initiate different loopback commands. Loopbacks are a simple, yet effective method to locate the source of alarms and errors, and are often the quickest route to resolve a problem. Several pre-defined codes (Inband, ESF FDL, HDSL and USER) are available to loop up/down network elements and this can quickly identify impaired spans over a large area. The DS1 receiver can be used to monitor a live T1 circuit for status and alarms throughout the network.

The real-time View RX Data feature or ABCD bits display quickly help find timing and protocol problems in CAS type signaling protocols. Talk and listen operations as well transmitting and measuring tones on an individual user defined PCM channel is possible in the Advanced Tools mode. TIMS measurements including Level and Frequency can be performed to identify problematic timeslots. The option provides key functionality necessary for testing and troubleshooting T1 Primary Rate connections. Operating in TE or NT modes, the unit is able to setup and receive ISDN calls with user-defined parameters including call control protocol, called number and related facilities. Protocol functions feature detailed signaling statistics, message monitoring and decode, and complete result presentation.

Equipped with these capabilities, analysis of international and national ISDN, and other access protocols is possible. Triple Play services are IP centric, so IP test functions are no longer considered a luxury. IP verification on the CX350 is possible over the DOCSIS Cable Modem and 10/100Base-T Ethernet test ports, while a subset of these tools is available using the USB WiFi adaptor. Take advantage of the three software options offering different test methods to verify and provision your VoIP network. Testing can be performed over any of the Ethernet or DOCSIS test ports.
