My code starts like this
import pyvisa as visa import os
rm = visa.ResourceManager('C:\Program Files (x86)\IVI Foundation\VISA\WinNT\agvisa\agbin\visa32.dll') my_connect = rm.open_resource("USB0::0x2A8D::0x0B0B::MY47191118::0::INSTR")
I am trying to control my Keysight Signal Analyzer using VISA.
When I try to run my python code it throws me this error.
Traceback (most recent call last): File "C:\Users\kolap\Downloads\MeasurementControlCode\MeasurementControlCode\scan_signal_analyzer.py", line 45, in
