I would like to use a RIGOL MSO5000 Series Scope as a 4 Channel DMM.

The device responds to *IDN? as expected, but there is a decoding issue for :WAV:DATA?

import pyvisa

rm = pyvisa.ResourceManager()

scope = rm.open_resource("USB0::0x1AB1::0x0515::MS5A233404321::0::INSTR")

print("" + scope.query("*IDN?"))

scope.write(":RUN")
scope.write(":WAV:SOUR CHAN1")
scope.write(":WAV:MODE NORMal")
scope.write(":WAV:FORM BYTE")
print(scope.query(":WAV:DATA?"))

scope.close()

Error

Exception has occurred: UnicodeDecodeError
'ascii' codec can't decode byte 0x80 in position 11: ordinal not in range(128)

UnicodeDecodeError: 'ascii' codec can't decode byte 0x80 in position 11: ordinal not in range(128)

The error persists even if I try

print(scope.query(":WAV:DATA?").decode(errors='ignore'))
print(scope.query(":WAV:DATA?").decode('utf8', errors='ignore'))
print(scope.query(":WAV:DATA?").read(encoding='CP-1252'))
