Step 2. Operator's Check
Description
The operator's check consists of two softkey initiated tests: Op Ck Port 1 and
Op Ck Port 2.
A short is connected to port 1 (port 2) to reflect all the source energy back into
the analyxer for an SU (E&2) measurement.
The first part of OP CK PORT 1 checks the repeatability of the transfer switch.
An SII measurement is stored in memory and the switch is toggled to port 2 and
then back to port 1 where another SII measurement is made The difference
between the memory trace and the second trace is switch repeatability.
The remaining parts of both tests exercise the internal attenuator in 6 dB steps
over a 55 dB range.
The resulting measurements must fall within a limit testing window to pass the
test. The window size is based on both source and receiver specillcations
The operator's check determines that:
1. The source is phase-locked across the entire frequency range
2. All three samplers are functioning properly.
3. The transfer switch is operational.
4. The attenuator steps 6 dB at a time.
