Cable Modem Network Analyzer
Find Slow Surf Problems quickly and Easily
The CM1000 Cable Modem Network Analyzer is an installation and troubleshooting tool that fully tests DOCSIS Cable Modem installations. Unlike other instruments that use signals unrelated to the DOCSIS system, the CM1000 uses a built in cable modem to fully exercise the network on both the downstream and upstream paths. The CM1000 communicates with the Cable Modem Termination System (CMTS) to characterize the digital performance in both directions. In addition to conventional digital tests such as MER, BER, level and Constellation on the forward path, a new proprietary Sunrise technology allows Block Error Rate (BkER) testing on the return path without a headend unit.
With this new return BkER technology, technicians will, for the first time, be able to characterize the return path modem performance. In addition, with the CM1000's full color display, technicians can determine at a glance whether the connection meets minimum requirements. By checking the various points in the network, the technician can quickly determine which components need to be replaced to ensure optimum performance.
Increase network performance and customer satisfaction by using the CM1000 to systematically detect and locate impairments in your analog, digital video, VOD, cable modem and VoIP services - in real time, both upstream and downstream.
Continuous measurements reveal changing network conditions
Integrated Web Browser and PC Emulation option
VoIP option to verify, test and troubleshoot VoIP services
Modularity - easily upgradeable as requirements evolve
realVIEW option provides access to remote upstream measurements
Upstream spectrum with CPD, C/I & C/N measurements
Comprehensive digital analyzer with constellation, equalizer and frequency response displays
Full analog and digital SLM functions coupled with the ability to test cable modem services, such as VoIP, make the CM1000 the most comprehensive troubleshooting tool available. The built-in cable modem exercises the downstream and upstream network paths.
Easy-to-use pass/fail test screens indicate the problems quickly, so that adjustments, replacements and follow-up verification tests can be performed immediately. The CM1000’s in-band capabilities and continuous measurements simplify locating tough intermittent problems.
The CM1000’s rugged construction makes it ready to work whenever and wherever your technicians need it - no need to leave the meter turned on between uses, boot up time is less than 30 seconds. The integrated fan ventilation allows continuous meter operation. The CM1000 will operate continuously at up to 120°F ambient and can be used even in the heaviest rain. And when the sun is shining the improved LCD screen affords great screen visibility.
Test anywhere in the network - at the tap, ground block or set top - even use the CM1000 to substitute for the customer’s cable modem or PC and troubleshoot in-home wiring, routers, firewalls and hubs.
Lighten your workforce’s load with the CM1000 - it’s more versatile and easier to carry than a meter and a laptop for field testing. By using the Web Browser option your technicians can be more efficient by accessing your workforce management system.
The CM1000 can verify and troubleshoot VoIP services and the all important network QoS that VoIP requires. The CM1000 establishes the specified QoS connection to the CMTS and measures critical service parameters, such as latency, jitter and lost packets, from the customer premises to the CMTS or media gateway.

"SMART" One-Button Tests
The CM1000 now includes CM500-style SMART tests. The user programmable tests are used to automatically evaluate network performance and to provide consistent and comprehensive testing. All test results can be saved and uploaded over the network. SMART test setups and instrument configurations can be stored on the network and downloaded to any meter when needed, making configuration changes easy and keeping testing consistent.
Three SMART test locations are provided, each with its own set of programmable tests and pass/fail limits. SMART tests may include analog and digital level scans (with custom channel plans), digital MER and BER, and complete cable modem tests. These one-button tests are a great way to quickly and consistently run a series of tests to ensure that the network is meeting performance requirements and has sufficient safety margins to keep running.
....when a DOCSIS system slows down or begins failing, there are four possible problems areas: Downstream, Upstream, Network and Modem/PC.
The CM1000 connects to the CMTS and records every step of the connection process so problems can be quickly identified and resolved. If any step fails to complete, errors are reported. View the IP details to ensure that the TFTP process completed properly and that the modem received the correct configuration during provisioning.
Once connected, all major upstream and downstream path parameters are displayed on the CM1000’s color LCD screen. Results within user programmed limits are displayed in green; results outside of the limits are displayed in red.
Additional results screens allow the technician to drill down to the details that identify specific network problems. The new Stats Mode displays upstream and downstream performance statistics. The user can view up to sixty measurement statistics made on one minute or one hour intervals. The worst-case measurement is graphed for each time period to capture performance data and aid in troubleshooting intermittent faults.
IP Tests: IP PING and Trace Route tests are included to aid in network connectivity analysis and troubleshooting. Use PING to test network integrity and Trace Route to identify network routes.
PC Emulation: Use the PC emulator to ensure the modem is providing the user’s PC with a routable IP address. Make an FTP connection to upload test results or download CM1000 configuration data. Use the optional web browser to demonstrate network connectivity using the RF or Ethernet interface.
Display the QAM modulated signal and use the CM1000’s exclusive Automated Diagnosis function to identify downstream impairments. Automated Diagnosis quickly and reliably identifies impairments such as noise, interference, phase noise, CSO, in-band spurs, laser clipping, and gain problems. Equalizer stress and frequency response screens are also provided for complete downstream troubleshooting.
MER Modulation error ratio provides early detection of non-transient, digital impairments including system noise, CSO, CTB, ingress and modulator problems. The CM1000’s pass/fail display allows technicians to quickly detect if MER meets recommended system levels for 64 QAM or 256 QAM signals. As the number of subscribers increases or VoIP services are deployed, ensuring adequate MER becomes more critical than ever. Poor MER can result in degraded modem performance, due to excessive packet retransmissions, and resultant customer dissatisfaction. Never risk falling over "the digital cliff"; the CM1000 helps you make sure that you have a safe operating margin.
PRE- AND POST-FEC BIT ERROR RATE (BER)
The CM1000’s BER display is especially useful for tracking down transient problems such as intermittent ingress and laser clipping. Verify the occurrence of downstream errors with the pre-forward error correction bit error rate (PreBER). Determine if the FEC function is successfully working with the post-FEC BER (PstBER). The display indicates errored seconds for pre- and post-FEC correction. If the errors are not correctable, a Severely Errored Second is displayed— an indicator of poor network performance.
For more information on QAM constellations, MER and BER, go to our Online CATV Training page.
The downstream Spectrum Analyzer provides a spectral view of any 64, 32, 16 or 8 MHz span in the 50 to 870 MHz range. View signal, Ingress or Distortions on the network and use the markers to measure analog or digital signals, CC/N (carrier to noise) or C/I (carrier to ingress). Setup allows the user to select the peak detector for analog signals or select the average detector and set the occupied bandwidth for accurate digital level measurements.
Characterize the return path from any point in the network by measuring in-service performance with the Upstream Block Error Rate (BkER) measurement.
Characterize the upstream performance and ensure that noise and ingress do not impair upstream data rates; measurements include: upstream BkER, transmitted, received, discarded and lost packets.
The CM1000 displays the upstream transmit power required at the test location and will calculate the system attenuation back to the CMTS. The user can ensure the optimum transmit level, assure an appropriate safety margin, and optimize the return path attenuation for maximum ingress reduction. The CM1000 will even calculate the correct value for reverse path step attenuators.
Eliminate slow uploads due to return path ingress, noise and CPD. The Upstream Spectrum feature offers the simplest automated method for testing and troubleshooting the return path. Use the CM1000 to measure bursty TDMA return signals, intermittent ingress, noise and CPD (common path distortion). Simply set the markers and the CM1000 does all the work, reading out the carrier level of TDMA signals, CPD or ingress, C/I ratio and C/N ratio.
Your technicians know the return path is often the most demanding portion of the network. Let the CM1000 simplify their job with the simplest, automated return path test and troubleshooting process in the field. Set the markers and let the CM1000 provide a simple pass/fail indication or use it to troubleshoot any portion of the return path.
An Ingress screen displays the ingress level, noise level and margin between these and the programmed pass/fail limits. Markers are pre-programmed, but may be repositioned by the user.

The CM-VoIP+™ option allows the CM500 and CM1000 to connect to the network and establish dynamic QoS upstream and downstream UGS service flows. The meter connects to the realMOS™ Server, transmits and receives UDP/RTP VoIP voice data to measure the Voice Quality of the network. Measurements, accessed directly from the Cable Modem Check mode, include MOS (mean opinion score), R-Factor, Latency, Jitter and Lost Packets—both upstream and downstream.
The CM transmits actual voice data over the QoS flow to the realMOS server, which then analyzes the voice quality. The realMOS server transmits voice data back to the CM for voice quality analysis. Results from the realMOS™ Server are then transferred to the CM via a TCP/IP connection. Measurements are then displayed for both the upstream and downstream.
