A15 Front End Control Assembly Troubleshooting

Verifying the Front End Control Assembly requires the RF Front End

Troubleshooting board E4410-60115 or kit number N9020-60005. The kit

includes the troubleshooting board and associated interconnect cables. The

troubleshooting board and cables will help verify the control logic from this

assembly to Input Attenuator A, Input Attenuator B, Low Band Switch, YTF

Preselector, (Optional) Low Band Preamplifier, (Optional) High Band

Preamplifier, (Optional) Electronic Attenuator and the RF Front End Assembly.

The control logic should be verified going to each assembly while the Front End

Troubleshooting board is connected.

If the EFEC is installed, the remaining control voltages and RF signals can be

measured directly with a voltmeter, oscilloscope, or functioning spectrum

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.
