Test 2: Channel 2 Frequency Sensitivity
Repeat steps 6, through 8 for each of the remaining frequencies specified
for Test 2a. Don't forget to change the power level when performing the
300 MHz and 19 GHz tests (53147A, 53148A, and 53149A) and the
16 GHz and 19 GHz tests (53149A only).
It may be necessary to repeat Step 5.
If all of the frequency values you recorded for Test 2a are correct, mark
Pass in the Performance Test Record. If any of the frequency readings you
recorded are incorrect, mark Fail in the Performance Test Record.

Test 2b: 22 GHz to 26.5 GHz Frequency Sensitivity

This test is appropriate for the Agilent 53148A and 53149A.
Use the same test setup as described for Test 2a on page 1-23.
Set the output of the Agilent 83650B Synthesizer to the first frequency
specified for Test 2b in the Performance Test Record on page 1-40
(22 GHz).
Set the power output of the Synthesizer (read on the Power Meter) to a
power value 20 dBm above the value specified for Test 2b in the
Performance Test Record on page 1-40 (–5 dBm for the Agilent 53148A;
–7 dBm for the Agilent 53149A). (The added 20 dBm compensates for the
20 dB Attenuator.)
Record the frequency value read on the Counter (±1 count) for Test 2b in
the Performance Test Record on page 1-40.
Repeat steps 2, through 4 for each of the remaining frequencies specified
for Test 2b.
If all of the frequency values you recorded for Test 2b are correct, mark
Pass in the Performance Test Record for Test 2b. If any of the frequency
readings you recorded are incorrect, mark Fail in the Performance Test
Record.
