Troubleshooting the Analyzer	Agilent 35670A
To perform self tests

Step 3. Determine the probable faulty assembly and next test by comparing the analyzer’s symptoms to the following table.

	Intermittent failure					Intermittent, page 4-40

†The circuits for the output ports are located on the A10 Rear Panel assembly except for a few output buffers on the A7 CPU assembly. If replacing the A10 Rear Panel assembly does not fix the failure, the A7 CPU assembly is probably faulty.

channel analyzers. The A12 BNC assembly routes the signals connected to the Channel 1 BNC connector and Channel 2 BNC connector to the A1 Input assembly. The A12 BNC assembly also routes the source signal from the A5 Analog assembly to the Source BNC connector. The signal connected to Channel 1 should be between 0.19531 Hz to 102.4 kHz in single channel mode and between 0.097656 Hz to 51.2 kHz in two channel mode. The signal connected to Channel 2 should be between 0.097656 to 51.2 kHz. For both channels, the signal’s amplitude range must be between +27 dBVrms and –51dBVrms for full scale measurements. The source output signal can be random noise, burst random noise, periodic chirp, burst chirp, pink noise, or fixed sine.
