Description of Example
To program U1281A/82A using Python you will need the following:
>PyVisa installed and configured to your Python programming environment
>Keysight IO Library Suite installed on your PC
>Use the USB-to-IR cable supplied with U1282A or U1281A Digital Multimeter connected. Open Keysight Connection expert on your PC and check if the U1282A or U1281A is detected.
#make sure pyvisa is setup import visa #load visa lib and open connection rm = visa.ResourceManager() #In this example com port 7 is assigned to the USB-to-IR adapter #Address 'ASRL7::INSTR' is equivalent to com port 7. myU1282A = rm.open_resource('ASRL7::INSTR') #get U1282A Identification myU1282A.write("*IDN?") print myU1282A.read() #Get teh value of the primary display myU1282A.write("FETC?") print myU1282A.read() #close Connection myU1282A.close() print 'close instrument connection'
