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 Community

Here is a Python script that uses Qcodes Community to connect to a SMW 200A - B140 RF Signal Generator:

import qcodes as qc
from qcodes.instrument_drivers.rohde_schwarz.SMW200A import SMW200A

# Create an instance of the SMW200A instrument
smw = SMW200A('smw', 'TCPIP0::192.168.1.1::inst0::INSTR')

# Connect to the instrument
smw.connect()

# Print the instrument ID
print(smw.IDN())

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

# Set the power level to -10 dBm
smw.power(-10)

# Enable the output
smw.output(True)

# Disconnect from the instrument
smw.disconnect()

Note: Replace 'TCPIP0::192.168.1.1::inst0::INSTR' with the actual VISA address of your SMW 200A instrument.
