5On the Agilent 8702D:
aPress MEAS, INPUT PORTS, B, MENU, POWER, 4, x1.
bUsing the analyzer front panel knob, adjust the test port power for a reading
of 20.000 dBm on the Agilent 8902A.
cWait for the reading to stabilize.
6On the Agilent 8902A, press the blue shift key and SET REF.
If the Agilent8902A has drifted, adjust the analyzer front panel knob for a
power reading of 0.000 dBm on the Agilent 8902A.

aPress CAL, CALIBRATE MENU, RESPONSE, THRU.
bAfter the analyzer finishes the measurement, press DONE: RESPONSE.
cPress SAVE/RECALL, SAVE STATE.
dPress MARKER FCTN, MARKER MODE MENU, STATS ON.
8Set the Agilent 8496A to 0 dB.
9On the Agilent 8702D, press MENU, TRIGGER MENU, SINGLE.
10 Write the mean value (which appears on the analyzers display) in the Test
Port column of the Performance Test Record.
11 Write the Agilent 8902A readout in the 8902A column of the Performance
Test Record.
12 Calculate the difference between the Test Port 2" and the 8902A.
13 Take the absolute value of the calculated difference, and enter the result in the
Calculated Value column of the Performance Test Record.
14 Set the Agilent 8496A to the other attenuation settings listed in the
Performance Test Record, while repeating Step 9 through Step 13.
NOTE
Ignore the UNCAL displayed on the Agilent8902A. Thi s indicates that you are making
an approximate power level measurement. However, this is not a concern because you
will be making a relative power measurement.
