A15 Front End Control Assembly Troubleshooting

The N9020A, MXA Signal Analyzer utilizes an RF front end troubleshooting

board that can be used to verify some, but not all of the control circuitry on the

N9010A, EXA Signal Analyzer due to the additions of front end assemblies. The

troubleshooting board kit part number is N9020-60005 and includes the

troubleshooting board and required interconnect cables. If you have the

interconnect cables, you can order the board by itself using part number

E4410-60115. When using the troubleshooting board and cables on a EXA the

control logic for Input Attenuator A, Input Attenuator B, Low Band Switch and

some of the power supplies can be verified. The remaining control voltages and

RF signals can be measured directly with a voltmeter, oscilloscope or

functioning spectrum analyzer.

In order to verify the wide bandwidth I.F.'s and Aux I.F. output frequencies and

power levels the following specialty cables and connector will be needed:

Other standard cables and connectors need to be used to adapt to the

voltmeter or the RF input of the functioning spectrum analyzer.
