R&S <strong>FSQ</strong> Instrument Functions<br />

External Generator Control – Option R&S FSP-B10<br />

RECALL The RECALL softkey restores the instrument setting with which the calibration was<br />

carried out.<br />

This can be useful if the device setting was changed after calibration (e.g. center frequency<br />

setting, frequency deviation, reference level, etc.).<br />

The softkey is only available if:<br />

• the NETWORK mode has been selected<br />

• the memory contains a calibration data set.<br />

SAVE AS TRD<br />

FACTOR<br />

Remote command: CORR:REC<br />

SAVE AS TRD FACTOR uses the normalized measurement data to generate a<br />

transducer factor with up to 625 points. The trace data are converted to a transducer<br />

with unit dB after the transducer name has been entered. The number of points is<br />

defined by SWEEP COUNT. The frequency points are allocated in equidistant steps<br />

between start and stop frequency. The generated transducer factor can be further<br />

adapted in the menu SETUP – TRANSDUCER. SAVE AS TRD FACTOR is only<br />

available if normalization is switched on.<br />

Remote command: CORR:TRAN:GEN '<br />

4.8.3 Reflection Measurement<br />

Scalar reflection measurements can be carried out by means of a reflection-coefficient<br />

bridge.<br />

4.8.3.1 Calibration of Reflection Measurement<br />

The calibration mechanism essentially corresponds to that of the transmission measurement.<br />

CAL REFL<br />

SHORT<br />

The CAL REFL SHORT softkey starts the short-circuit calibration.<br />

If both calibrations (open circuit, short circuit) are carried out, the calibration curve is<br />

formed by averaging the two measurements and stored in the memory. The order of<br />

measurements is optional.<br />

After the calibration the following message is displayed:<br />
