Deactivation of Ports with remote commands

Question

I want to deactivate the measurment of unused ports to increase the speed. It can be done in the port configuration, but I have not found a corresponding remote command to do that.

Is there a remote command to remove the "meas" flag for a certain port?

Answer

There are two possibilities to deactivate the "Meas" function of a port:

Perform a single port calibration. After the calibration is saved, the "meas" function of all other ports is deactivated. Here is a small SCPI sequence:

CORR:COLL:METH REFL1

CORR:COLL OPEN1

CORR:COLL:SAVE

The sequence performs a normalization with an open standard on port 1. After the last command the "Meas" flag is active for port 1 only.

If you do not want to perform a calibration, you may use that command:

SOUR:GRO:PORT 1
