Connect to the SR830 in Python

PROTOCOLS > SCPI

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.
