Restart Sweep on Std. Meas.
If this function is active, a new standard measurement initiates a new sweep, starting
at the beginning ("Start") of the sweep range: The sweep points for the calibration
sweep are in ascending order, like for an ordinary measurement.
If "Restart Sweep on Std. Meas." is inactive, the new standard measurement is started
at the current sweep point; the current sweep is continued as a calibration sweep.
Note:
This function has a secondary effect in IDLE mode (i.e. while the calibration sweep is
NOT running):
●
If active, only the selected trace is refreshed.
●
If inactive, the R&S ZNA permanently refreshes all traces of all diagrams which can
put a heavy load on the connected switch matrices (if any).
Hence it is recommended (and default) to activate it, in particular if one of the matrices
uses mechanical switches (that wear off apart from making noise).
Apply
Is enabled when sufficient data have been acquired for the calibrated ports and stand-
ards and for the power meter. The button starts the calculation of the calibration data
and closes the calibration wizard. The current instrument settings are stored with the
correction data.
To avoid incompatibilities, older calibration data is deleted unless it has been transfer-
red into the "Cal Pool" using the "Calibration Manager".
Note: Checks during the calculation of correction data
Incompatibilities between the selected calibration type, the standards and the channel
settings can cause the calibration to be inaccurate. The analyzer auto-detects potential
sources of errors and displays appropriate, self-explanatory notice boxes.
Remote command:
[SENSe<Ch>:]CORRection:COLLect:SAVE:SELected[:DUMMy]
[SENSe<Ch>:]CORRection:COLLect:SAVE:SELected:DEFault
[SENSe<Ch>:]CORRection:COLLect:DELete

Automatic calibrations
The calibration wizard can also guide you through a calibration using a calibration unit
(plus a power meter for SMARTer Cals).

1. For each port assignment:
a) Connect the calibration unit to the related set of test ports.
b) Perform an automatic system error correction.
