After the reference line has been shifted by entering REF VALUE –10 dB,
departures from the nominal value can be displayed with high resolution
(e.g. 1 dB / Div.). The absolute measured values are still displayed, in the
above example, 1 dB below nominal value (reference line) = 11 dB
attenuation.

RECALL
The RECALL softkey restores the instrument setting with which the
calibration was carried out.
This can be useful if the device setting was changed after calibration (e.g.
center frequency setting, frequency deviation, reference level, etc).
The softkey is only available if:
•
the NETWORK mode has been selected
•
the memory contains a calibration data set.

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
menu SETUP – TRANSDUCER. SAVE AS TRD FACTOR is only available
if normalization is switched on.
