Input Extensions (Vector Network Analyzers)
are the hardware configuration and setup parameters that apply to the Keysight 89600 VSA with Keysight Vector Network Analyzers.
To modify a hardware parameter, open the Input Extension dialog (tab), click the parameter name and specify the value.

UserScpiCommands
UserScpiCommands is useful for setting parameters on the Vector Network Analyzer that cannot be set directly from the 89600 VSA user interface.
SCPI commands can be entered separated by semicolons. SCPI Query commands are not supported.
The SCPI command string is saved in an 89600 VSA setup, which allows a customized instrument configuration set by the user SCPI commands to be recalled.
These setup commands must not change data acquisition or spectrum analysis parameters on the VNA channel used by 89600 VSA. 89600 VSA does not allow some SCPI commands or any queries in a UserScpiCommands string. An entry containing invalid commands or queries is replaced by an empty string.
An alternate method for customizing the instrument setup is to call the HardwareConfiguration.Suspend() method on the measurement's selected analyzer through the 89600 .NET API. This releases the exclusive VISA resource lock held by 89600 VSA. While 89600 VSA is suspended, SCPI commands, including queries, can be sent to the instrument by a macro or another application. 89600 VSA re-acquires an exclusive VISA resource lock on the instrument when any operation is performed on the 89600 VSA measurement. While 89600 VSA is suspended, SCPI commands sent must not change data acquisition or spectrum analysis parameters on the VNA channel used by 89600 VSA. It is fully the user's responsibility to ensure that no invalid commands are sent and that any VISA resource lock on the instrument held by another application is unlocked before the 89600 VSA measurement is resumed. Any instrument setup customization performed while 89600 VSA is suspended is not part of 89600 VSA state and so cannot be saved and recalled with a setup file.
