How to troubleshoot the analyzer

•Review ‘’Safety Considerations’’ and ‘’Troubleshooting Hints.’’

Service must be performed by trained service personnel who are aware of the hazards involved (such as fire and electrical shock).

•See chapter 6, ‘’Replacing Assemblies,’’ to determine how to disassemble and assemble the analyzer.

•Determine initial test by comparing the analyzer’s symptoms to the symptoms in the following table.

Symptom	Troubleshooting Test


Screen blank †	Initial verification, page
Screen defective	4-5
After power up, >3 minutes before keys active
No response when key is pressed
Incorrect response when key is pressed

Keys are active and screen grid is displayed but screen is defective	Display, page 4-22

Error messages	Self tests, page 4-31
Calibration fails
Performance test fails
Intermittent failure
GPIB fails
Mic pwr fails
Serial port fails
Parallel port fails
External monitor does not work

External keyboard does not work	DIN connector, page
	4-61

External trigger fails	Trigger, page 4-62

Nonvolatile states not saved after power cycled	Memory battery, page
Date display is ‘’Date: 01-01-BL’’	4-67

†If the analyzer is failing, the grid may not appear for two minutes. Wait two minutes before assuming that a low level failure occurred.

•Follow the recommended troubleshooting test until you locate the faulty assembly.

•Replace the faulty assembly and follow the directions in ‘’What to do after replacing an assembly’’ in chapter 6, ‘’Replacing Assemblies.’’

OutputTachometer Input External Trigger InputA11 Keyboard Controller Signal NameA11 Keyboard Controller assembly Agilent 35670AThe A12 BNC assembly is only used in two 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.
