Connecting to R&S SGS100A by Rohdes&Schwarz in Python

Instrument Card

The R&S®SGS100A is an RF source designed to meet the requirements of automated test systems. It is available as a CW source or as a vector signal generator with an integrated I/Q modulator. With its frequency range of up to 12.75 GHz, the vector signal generation version covers the essential digital signals. The CW version can be used as a flexible local oscillator and for interference testing against mobile radio standards.

Read our guide for turning Python scripts into Flojoy nodes.

Flojoy

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

Here is a Python script that uses Qcodes to connect to a R&S SGS100A RF Signal Generator:

import qcodes as qc
from qcodes.instrument_drivers.rohde_schwarz.SGS100A import RohdeSchwarzSGS100A

# Create an instance of the instrument
sg = RohdeSchwarzSGS100A('sg', 'TCPIP0::192.168.1.1::inst0::INSTR')

# Connect to the instrument
sg.connect()

# Print the frequency of the signal generator
print(sg.frequency())

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

# Turn on the RF output
sg.on()

# Turn off the RF output
sg.off()

# Disconnect from the instrument
sg.disconnect()

Note: Replace 'TCPIP0::192.168.1.1::inst0::INSTR' with the actual address of your signal generator.
