Additional conditions for repeating a calibration
Changing the channel settings can cause incompatibilities between the current instrument state and the
previous calibration. In particular the following conditions must be met:
•
The configuration of all ports needed must be correct (see Select Connector – Physical Port
Number #) .
•
The Sweep Type must be unchanged.
If incompatible settings occur the analyzer displays an error message and does not repeat the
calibration.
Recall Last Cal Set
•
Loads and activates the setup for which the last calibration was performed. If the last
calibrated setup is already active, nothing is changed.
•
The calibrated setups are automatically stored in the
C:\Rohde&Schwarz\Nwa\Calibration\RecallSets directory. A message box pops up if the
directory is empty, e.g. because no calibration was performed yet.
Correction Off
Activates or deactivates the system error correction in the active channel. Correction Off is active only if
a valid system error correction is assigned to the active channel; see Cal State in the Calibration
Manager.
A red label Cal Off ! appears behind the trace list if the system error correction is switched off;
see also Calibration Overview.
