PROTOCOLS > SCPI

📄 IDN

Query a device's identity through the universal *IDN? SCPI command.

📄 MEASURE VOLTAGE

Query an instrument's measured output voltage, such as a DMM or power supply.

📄 SCPI WRITE

Write a SCPI command to a connected bench-top instrument and return the result.

QCodes

To connect to a Keysight 34934A DAQ board using Qcodes, you can use the following Python script:

from qcodes import VisaInstrument

# Connect to the DAQ board
daq = VisaInstrument('DAQ', 'TCPIP0::192.168.1.1::inst0::INSTR')

# Create an instance of the Keysight34934A module
module = Keysight34934A(daq, 'module1', 1)

# Set the relay protection mode to 'AUTO100'
module.protection_mode('AUTO100')

# Get the relay protection mode
mode = module.protection_mode()

# Print the relay protection mode
print(f"Relay protection mode: {mode}")

# Disconnect from the DAQ board
daq.close()

Note: Make sure to replace 'TCPIP0::192.168.1.1::inst0::INSTR' with the actual VISA address of your DAQ board.
