The manual for the Sencore CM2000 Computer Monitor Analyzer provides instructions on setting up and operating the device to test composite NTSC monitors, including selecting the proper input signal, connecting the analyzer to the monitor, and choosing video patterns for testing. It also covers troubleshooting steps such as adjusting blanking timing parameters to ensure accurate display positioning and storing new formats for future use.
Manual Overview
The Sencore CM2000 Computer Monitor Analyzer is designed to test composite NTSC monitors by generating a standard 1 volt peak-to-peak composite video signal. To begin testing, set the video format switches to analog and ensure the sync adders are on, while interlace and video output are off. The CM2000 allows for manual adjustment of blanking timing parameters to match NTSC standards, which is crucial for accurate testing. Users can enter specific vertical and horizontal sync parameters to customize the timing for non-standard monitors. Error code “E1” will appear if vertical sync frequency is set incorrectly in manual mode. Once parameters are set, they can be stored in memory locations 20 to 39 for future use. When connecting the analyzer to the monitor, use the appropriate adapter for the monitor’s input jack. The CM2000 provides various video patterns for testing, but note that color bars will appear monochrome due to the absence of a chroma subcarrier signal. For further guidance, refer to the CM2000 Operation and Application Manual.
Quick Issues Covered
- Diagnose composite NTSC monitor issues with CM2000 Analyzer.
- Adjust blanking timing for off-center test patterns.
- Error code 'E1' appears in manual blanking timing mode.
Overview
The product discussed is the CM2000 Computer Monitor Analyzer, which is used for testing computer and video monitors that use a composite input signal conforming to the NTSC standard. The manual covers how to select the proper input signal for a composite monitor, connect the CM2000 to the monitor input, and select video patterns for testing. It also explains how to adjust the signal parameters and change blanking timing to match NTSC standards.

Operation
The CM2000 Computer Monitor Analyzer is used for testing composite NTSC monitors by providing a standard 1 volt PP composite video signal. To set up the CM2000 for testing, adjust the video format switches to “analog” and “+”, set sync adders to “on”, interlace to “off”, and video output to “off”. The device can automatically set blanking timing to a default condition, but users can manually adjust these parameters to match NTSC standards. Video patterns for testing will appear monochrome on both monochrome and color monitors due to the absence of a chroma subcarrier signal. To connect the CM2000 to a monitor, use connector cable #6 and appropriate adapters if necessary. Users can store and recall custom formats in memory locations for future use.
