5.1.7. Dynamic Level Accuracy (R3755A/R3755TF)
Measurements of the analyzer are expressed as vector data, so the dynamic level accuracy of phase charac-
teristics is assured by magnitude characteristics satisfying standards. As a result, this section explains the
method for confirming the dynamic level accuracy of magnitude characteristics.
Testing Procedure
Dynamic Level Accuracy
29.
Connect the 3 dB fixed attenuator and step attenuator to OUTPUT and INPUT
respectively by using the RF cables as shown in the figure below:
Figure 5-4 Dynamic Level Accuracy
30.
Set PI circuit to OFF, center frequency to 11 MHz for R3755A, or 9 MHz for
R3755TF, frequency span to 0 Hz, output power to 6 dBm, and RBW to 30 Hz.
31.
Set the step attenuator to 20 dB.
32.
Execute Thru normalize.
33.
Set the step attenuator to 0 dB.
34.
Acquire the Trace data using a marker.
