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

from qcodes import Station, Instrument
from qcodes.instrument_drivers.Keysight.N51x1 import N51x1

# Create a station to hold the instrument
station = Station()

# Connect to the Keysight N5171B EXG RF Signal Generator
n5171b = N51x1('n5171b', 'TCPIP0::192.168.1.1::inst0::INSTR')

# Add the instrument to the station
station.add_component(n5171b)

# Print the IDN information of the instrument
print(n5171b.get_idn())

# Set the frequency to 1 GHz
n5171b.frequency(1e9)

# Set the power to -10 dBm
n5171b.power(-10)

# Enable the RF output
n5171b.rf_output(1)

# Disable the pulse modulation
n5171b.pulse_modulation(0)

# Disconnect from the instrument
n5171b.close()

This script connects to a Keysight N5171B EXG RF Signal Generator using the Qcodes driver N51x1. It creates a station to hold the instrument, connects to the instrument using the instrument’s IP address, adds the instrument to the station, and then performs various operations on the instrument such as setting the frequency, power, enabling RF output, and disabling pulse modulation. Finally, it closes the connection to the instrument.
