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

QCodes Community

Here is an example Python script that uses Qcodes Community to connect to a RFSG RF Signal Generator:

import qcodes as qc
from qcodes_contrib_drivers.drivers.NationalInstruments.NIRFSG import NI_RFSG

# Connect to the RF Signal Generator
rfsg = NI_RFSG("rfsg", "PXI1Slot2")

# Print the IDN information
print(rfsg.get_idn())

# Set the frequency and power level
rfsg.frequency(1e9)  # 1 GHz
rfsg.power_level(-10)  # -10 dBm

# Enable the RF output
rfsg.output_enabled(True)

# Close the connection
rfsg.close()

Note: Make sure you have installed the qcodes_contrib_drivers package before running this script.
