"File Format": 1.0

"Device Identification":
{
"Settling Time": 0.03
},
"Commands":
[
{ "Command Name": "MySetting1",
"Command List":

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.
4.7.41 External DLLs
The R&S ZNA firmware provides a plug-in interface that allows you to extend the VNA
firmware with custom functionality (measurements, device control, ...) .
The plug-in interface allows the external software to interact with the firmware before
and after a change of the:
●
channel
●
drive port
●
sweep segment
●
sweep point
The plug-in then can perform arbitrary actions and eventually return data to the VNA
firmware:
●
as custom traces
Optional extensions and accessories
