Description: Script to set up the external Trigger of the NRP18SN to sender mode.
As soon the power level at the NRPXXS(N) exceeds the set trigger level a trigger is executed at the SMB output port.

Requires: R&S NRP18SN, FW 2.30 or newer
- Installed RsInstrument Python module (see the attached RsInstrument_PythonModule folder Readme.txt)
- Installed VISA e.g. R&S Visa 5.12.x or newer

General Information:
This example does not claim to be complete. All information has been
compiled with care. However errors can not be ruled out.
