Restore Calibration Settings
The calibration remains valid if the start frequency,
stop frequency, center frequency and span are
subsequently changed within the calibrated
frequency range 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 range 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 saving a data set for a vector or a scalar
refl ection measurement in a calibrated state, the
R&S FSH can store the calibration data along with
the other settings. Thus, after the setting is recalled,
a measurement can be performed without prior
calibration.
