The service manual for the CMT-B10 AF analyzer provides detailed instructions on setting up, operating, and troubleshooting the device, including switching between operating modes, adjusting frequencies, and outputting measurement results. It also includes guidance on testing and adjusting broadband and narrow-band measurements, as well as troubleshooting specific components like data channels and connectors.
Manual Overview
The service manual for the CMT-B10 AF analyzer provides detailed instructions for technicians on troubleshooting, diagnostics, and calibration. The manual emphasizes the importance of understanding the troubleshooting flow, particularly through the use of a troubleshooting diagram, which aids in identifying issues related to data channels, coaxial connectors, and multipoint connectors. Error codes and diagnostics are crucial, with specific messages such as “CHECK INST.” indicating issues with signal levels at the analyzer input. Calibration and adjustments are covered, including broadband and narrow-band measurement adjustments, ensuring accurate readings. The manual also provides board-level guidance, detailing the function of components like the input amplifier, band-limiting filter, mixer, and IF conditioning. Switching between operating modes, such as SSB and DEMOD analysis, is facilitated by SPEC functions, and technicians are advised to ensure the Adjacent-channel Power Meter is off during CMT-B10 operation to avoid RF synthesizer interference. The manual underscores the importance of accurate frequency and amplitude settings for precise measurement outputs.

Operation
The manual provides information on the operation of the CMT-B10, a digitally controlled AF analyzer. It describes the connection and application of the option, noting that there is no direct relationship between RF level and measured AF level due to RF level control to prevent overdriving in the mixer. The analyzer can handle frequencies from 300 Hz to 15 kHz and is capable of analyzing modulation spectra for unwanted distortions and intermodulations.
To switch on the analyzer in SSB mode, the function 150 SPEC is used, and the analyzer outputs a level value and associated frequency on the display. If the AF signal is too small or too large, a “CHECK INST.” message prompts the user to check the test setup.
Switching between operating modes involves using specific SPEC functions, with SSB mode being the default after a master reset. The manual also notes that the Adjacent-channel Power Meter (CMT-B6) must be switched off during operation of the CMT-B10 to avoid interference with the RF synthesizer.
Measurement results are displayed alphanumerically, showing the level of the measured spectral line, associated frequency, and sideband information.
