Chapter 6, Problem Solving

If you have a problem testing your radio

This section contains information for solving some of the most common problems

related to using the HP 11807A,E radio-test software. All problems in this section

have a single obvious symptom (shown in bold typeface at the top of each page),

but many possible causes (listed in order from the most probable cause to the least

probable cause).

NOTE: If the test set displays an error that states “One or more self-tests failed”, you have a

hardware problem. In this case, refer to the test set’s Assembly Level Repair manual.

If the problem has to do with operating the test set, you’ll want to refer to the

MESSAGE screen to list errors or operating messages that have occurred since

the instrument was turned on. To do this, press the SHIFT and then the MSSG

key.

Also, the HP Instrument BASIC manual describes any errors that happen as a

result of running IBASIC programs.
