12. Receiver Magnitude Dynamic Accuracy
25.Calculate the dynamic accuracy for each attenuator setting by using the formula:
|G − F| (the absolute value of the difference between the values in column “G” and
column “F”).
Channel A Magnitude Dynamic Accuracy
To measure the magnitude dynamic accuracy of channel A, the test set is switched to route
transmitted power to the A sampler of the analyzer (an S
12
measurement at port 1 and
port 2 of the test set). Before channel A’s magnitude dynamic accuracy can be measured, a
power meter calibration and full two-port calibration must be performed for this new
signal path.
Power Meter Calibration for Channel A
1. Connect the equipment as shown in Figure 2-25. Be sure to remove the cable from the
channel A connectors.
