Troubleshooting the Analyzer
Using the Internal Service-Diagnostic Routines
Verify the −10 V reference detector
This service-diagnostic routine verifies the −10 V reference. −10 V is
summed with the tuning voltages and used in the main coil driver and
originates on the A7 analog interface board assembly. Frequency and
amplitude errors will occur if this voltage is incorrect.
Verify the −10 V reference detector by pressing
−10V REF DETECTOR.
• If the signal trace is at the bottom of the display, the −10 V
reference detector is functioning properly. See Figure 4-14.
• If the signal is not at the bottom of the display, the problem is
isolated to the A7 analog interface board assembly. Refer to
Chapter 6 for further troubleshooting.
