Test 3: Channel 2 Frequency Sensitivity

Test 3c: 30 GHz to 46 GHz Frequency Sensitivity

This test is appropriate for the 53152A Counter only.
Use the same test setup as described for Test 3a on page 1-21.
Set the output of the Agilent 83650B Synthesizer to the first frequency
specified for Test 3c in the Performance Test Record on page 1-31
(30 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 3c in the
Performance Test Record on page 1-31 (–3 dBm). (The added 20 dBm
compensates for the 20 dB Attenuator.)
Record the frequency value read on the Counter (±1 count) for Test 3c in
the Performance Test Record on page 1-31.
Repeat steps 2, through 4 for each of the remaining frequencies specified
for Test 3c. Don't forget to change the power level for the 42, 44, and
46 GHz tests.
If all of the frequency values you recorded for Test 3c are correct, mark
Pass in the Performance Test Record for Test 3c. If any of the frequency
readings you recorded are incorrect, mark Fail in the Performance Test
Record.
• Do not disconnect the Power Sensor or the Power Sensor Cable from
the power meter or the Power Splitter. These connections are reused in
the following tests.
• Do not turn off the Counter. Turning the Counter off and back on
resets the reference oscillator (REF OSC) selection to internal (INT).
