b) When the connect diagram is displayed,

check hardware and connections.

1) Connect scope to monitor port of 70420A

test set.

2) Set scope to monitor waveform.

3) Connect the signal paths to the phase noise

test set.

4) Set quadrature (set the signal to zero volts

on scope and a null on View Meter).

c) Select Continue.

d) When prompted by the software, connect the

calibration signal from the calibration source

to the coupler, then select Continue.

e) When prompted by the software, disconnect

the calibration signal from the calibration

source, then select Continue.

8. When the measurement is complete, print the

results and save the measurement file.

9. Interpret the results. Note the PRF feedthrough,

aliasing effects, and any breaks in the graph. If

PRF feedthrough is high and there are breaks in

the graph, set the LNA Gain to 56 dB of gain and

watch for clipping on the monitor oscilloscope.

Start a Repeat measurement and adjust the quad-

rature at the connect diagram.
