The calibration for the transmission measurement
is not lost if the start, stop frequency, the center
frequency and the span are subsequently changed
within the calibrated frequency domain. In this
case, the R&S FSH interpolates the correction data
between the reference points of the calibration. In
this case, the R&S FSH displays (Approx) at top left
and indicates the possibly increased measurement
error. If the modifi ed frequency domain lies outside
the calibrated frequency range, the calibration
becomes invalid and (UNCAL) is displayed at top
left. To restore the last valid calibration, proceed as
follows:
Press the CALIBRATE softkey in the main menu
for the network analyzer.
Select RESTORE CALIBRATION SETTINGS with
the rotary knob or the cursor keys (
∧
or
∨
).
The R&S FSH restores all instrument settings
which were used at the time of the last calibration.
The calibration is reactivated and (CAL) is
displayed at top left.
When a data record for scalar refl ection
measurement in calibrated state is saved, the R&S
FSH also discards the calibration data with the
remaining settings. This means that it is possible to
measure without fi rst having to recalibrate after the
settings have been restored.
