An identical "Settling Time" is used for all command sequences within a device config-
uration file. If certain command sequences require a significantly longer/shorter settling
time, it is recommended to declare them in a separate config file.

External DLLs
The R&S
ZNA firmware provides a plug-in interface that allows you to extend the VNA
firmware with custom (measurement) functionality.
The plug-in interface allows the external software to interact with the firmware:
●
at the begin of a sweep
●
at the end of a sweep
●
at every sweep point
The plug-in then can perform arbitrary actions and eventually return data to the VNA
firmware:
●
as traces
●
as input values for math functions for the calculation of other traces
