Cal Power Offset
See "Cal Power Offset" on page 593.
M. Source Att.
See "Source Step Att." on page 526.
If an external switch matrix is used, the attenuation settings of the matrix test ports that
can be connected to the same VNA port are coupled:
●
"M. Source Att." can only be applied, if all these ports are equipped with source
step attenuators.
●
The firmware enforces identical attenuation settings for those ports.
For matrix connectivity, see Chapter 4.7.41.3, "RF connections and matrix connectiv-
ity", on page 325.
El. Source Att.
The R&S ZNA comes with an electronic step attenuator in the source path of each
port. You can either select one of the possible attenuation factors (0 dB, 20 dB, 40 dB)
or select "Auto" to let the firmware decide (default).
If an external switch matrix is used, the attenuation settings of the matrix test ports that
can be connected to the same VNA port are coupled. The firmware enforces identical
attenuation settings for those ports.

Remote command:
SOURce<Ch>:POWer<Pt>:EATTenuation:MODE
SOURce<Ch>:POWer<Pt>:EATTenuation
ALC
Enables/disables automatic level control (ALC) for the current channel.
Same functionality as "ALC ON" on the Power tab or in the ALC Config dialog.
Remote command:
SOURce<Ch>:POWer:ALC:CSTate
ALC Params
Displays the current ALC parameters. Click on the table cell to open the ALC Config
dialog that allows you to (enable and) configure automatic level control (ALC) for the
current channel.
Slope
Defines a linear factor to modify the port-specific source power as a function of the
stimulus frequency. The resulting output power at port frequency f is calculated as
<Power Result> + <Slope> * f.
