Using Option EXM with the Keysight 11970 Series Mixers.
Amplitude calibration
See “Loading conversion loss data for the PXA Signal Analyzer” on page 161.
This will guide you through entering the conversion loss data provided with the
mixer, into a corrections file that can be activated to provide amplitude corrected
measurements.
NOTE Assure only ONE correction file is turned on because it is possible to turn on
multiple correction files, and if some of the files share the same frequency points, the
correction that results for those shared frequency points will cause measurement
errors. Therefore assure that only the correction file required for the measurement is
turned on, and turn off all other corrections.
Loading conversion loss data for the PXA Signal Analyzer
The conversion loss data supplied with your mixer can be loaded into your signal
analyzer from one of two sources:
7 Tune the analyzer to the
input signal frequency
a. Press FREQ Channel.
b. Enter a center frequency or a start
and stop frequency
8 Turn on the Signal ID
function
• Press Input Output, External
Mixing, Signal ID Mode, Image
Suppress, Signal ID On.
This enables you to identify true
signals from images and
harmonics.
See “Signal ID” on page 166
for more information.
