A15 Front End Control Assembly Troubleshooting
The NFA Series utilizes an RF front end troubleshooting board that can be used
to verify some, but not all of the control circuitry on the 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, 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.
