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

To connect to a SR830 Lock-in Amplifier using Qcodes, you can use the following Python script:

import qcodes as qc
from qcodes.instrument_drivers.stanford_research.SR830 import SR830

# Create an instance of the SR830 instrument
lockin = SR830('lockin', 'TCPIP::192.168.1.1::INSTR')

# Connect to the instrument
lockin.connect()

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

# Set the frequency to 1 kHz
lockin.frequency(1000)

# Set the sensitivity to 10 mV
lockin.sensitivity(0.01)

# Enable the front panel
lockin.enable_front_panel()

# Read the X and Y values
x = lockin.X()
y = lockin.Y()

# Print the X and Y values
print(f'X: {x}, Y: {y}')

# Disconnect from the instrument
lockin.disconnect()

This script creates an instance of the SR830 instrument and connects to it using the specified address (TCPIP::192.168.1.1::INSTR). It then sets the frequency and sensitivity of the lock-in amplifier, enables the front panel, and reads the X and Y values. Finally, it disconnects from the instrument.

Note: Replace 'TCPIP::192.168.1.1::INSTR' with the actual address of your SR830 Lock-in Amplifier.
