R&S ESU Instrument Functions
Tracking Generator – Option R&S FSU-B9
4.326 Operating Manual 1302.6163.12 - 03
RECALL The RECALL softkey restores the R&S ESU settings that were used during source
calibration.
This can be useful if device settings were changed after calibration (e.g. center fre-
quency, frequency deviation, reference level, etc.).
The softkey is only available if:
• the NETWORK mode has been selected
• the memory contains a calibration data set.
Remote command:
CORR:REC
SAVE AS TRD
FACTOR
SAVE AS TRD FACTOR uses the normalized measurement data to generate a
transducer factor with up to 625 points. The trace data are converted to a transducer
with unit dB after the transducer name has been entered. The number of points is
defined by SWEEP COUNT. The frequency points are allocated in equidistant steps
between start and stop frequency. The generated transducer factor can be further
adapted in the
SETUP menu – TRANSDUCER . The SAVE AS TRD FACTOR soft-
key is only available if normalization is switched on.
Remote command:
CORR:TRAN:GEN <name>'
