Port Assignment (manual)
The "Connections" step allows you to configure the assignment between VNA ports
and calibration unit ports manually.
The test port connectors are automatically set according to the connector type of the
selected calibration unit port.
Detect Port Assignment
Starts a procedure by which the R&S
ZNL/ZNLE (with a little help from the attached
calibration unit) auto-detects the connected ports. The automatic assignment replaces
the configured one.
If auto-detection fails because of a high attenuation in the signal path, you can either
enter the port assignment manually or connect matching port numbers and select
"Default Port Assignment".
Remote command:
[SENSe:]CORRection:COLLect:AUTO:PORTs:CONNection?
Default Port Assignment
Restores the default port assignment.
Start
.
If the configured port assignments are invalid, this action is disabled.
Step 3: Cal Unit
During the calibration phase, the R&S
ZNL/ZNLE displays a "Cal Unit" screen that
guides the user through the actual correction data acquisition.
In each calibration step
●
the calibration unit must be connected according to the depicted port assignment;
auto-detection is possible
●
the related test ports are calibrated with the "Calibration Type" selected in
●
a subsweep is performed for each required test port or port pair and every required
standard
After all these calibration steps have been completed, the resulting system error cor-
rection can be calculated and applied.
