If both calibrations (open circuit, short circuit) are carried out, the calibration trace is
calculated by averaging the two measurements. The order of the two calibration meas-
urements is irrelevant.

Calibrate Reflection Open
Starts an open-circuit reflection type measurement to determine a reference trace for
calibration.
If both reflection-type calibrations (open circuit, short circuit) are carried out, the refer-
ence trace is calculated by averaging the two measurements. The order of the two cali-
bration measurements is irrelevant.

Source Calibration Normalize
Switches the normalization of measurement results on or off. This function is only
available if the memory contains a reference trace, that is, after a calibration has been
performed.
For details on normalization see "Normalization" on page 336.

Recall
Restores the settings that were used during source calibration. This can be useful if
instrument settings were changed after calibration (e.g. center frequency, frequency
deviation, reference level, etc).

Save As Trd Factor
Uses the normalized measurement data to generate a transducer factor. The trace
data is converted to a transducer with unit dB and stored in a file with the specified
name and the suffix
.trd
under "
c:\r_s\instr\trd
". The frequency points are
allocated in equidistant steps between start and stop frequency. The generated trans-
ducer factor can be further adapted using the "Transducer" softkey in the SETUP
menu.
For more information on transducers see chapter 9.2, "Basics on Transducer Factors" ,
on page 566.
This function is only available if Source Calibration Normalize is switched on.
