lock out is checked by locking out the external reference and checking the external
reference lock detector.
RF Input/Output
RF In/Out to Aux RF Out Test
Using an external connection, the power is measured using the CW/AF Analyzer.
Aux RF Out to Aux RF In
Usingan external connection, the filter output detector level is measured by the voltmeter
through the voltmeter multiplexer.
Instrument Self Test
The power-up self tests are invoked internally.
Power Supplies On Measurement Board
The power supply sense points on the A19 Measurement assembly are read.
