5 Verify that the Counter is still set to use an external reference signal
(refer to steps 5 through 10 on page 1-13).
6 Set the output of the Agilent 83650B Synthesizer to the first frequency
specified for Test 3a in the Performance Test Record on page 1-31
(50 MHz).
7 Set the power output of the Synthesizer (read on the Power Meter) to a
power value 20 dBm above the value specified for Test 3a in the
Performance Test Record on page 1-31 (0 dBm). (The added 20 dBm
compensates for the 20 dB Attenuator.)
8 Record the frequency value read on the Counter (±1 count) for Test 3a in
the Performance Test Record on page 1-31.
9 Repeat steps 6, through 8 for each of the remaining frequencies specified
for Test 3a. Don’t forget to change the power level when performing the
400 MHz and 19 GHz tests (53150A, 53151A, and 53152A) and the
16 GHz and 19 GHz tests (53152A only).
