Procedure
(Attenuator Test: Option 26)
1.
C
onnect the 12000A to the measuring receiver via the downconverter. With the 12000A at
0 dBm and set to the first test frequency; set LO 21.4 MHz above UUT set frequency. Establish a
reference on the receiver in a tuned RF level mode. Reduce the 12000A output in 10 dB steps,
observing and recording the receiver reading. As needed, perform the recalibration requested by the
receiver.
2.
Repeat this procedure for the remaining test frequencies.

NOTE:
When measuring the flatness and accuracy of the model 12000A,
consideration must be given to the various measurement uncertainties in the test
system. These include, but are not limited to, VSWR, Cal Factor uncertainty and
calibration.
