Connect to the SR865A in Python

PROTOCOLS > SCPI

To connect to a SR865A Lockin Amplifier using Qcodes, you can use the following code:

from qcodes.instrument_drivers.stanford_research.SR865A import SR865A


# Create an instance of the SR865A driver
address = "TCPIP::192.168.1.1::INSTR"
lockin = SR865A("lockin", address)


# Connect to the instrument
lockin.connect()


# Now you can use the instrument to perform various operations
# For example, you can get the X and Y values
x = lockin.X()
y = lockin.Y()


# You can also set the frequency and amplitude
lockin.frequency(1000)  # Set the frequency to 1000 Hz
lockin.amplitude(0.1)   # Set the amplitude to 0.1 V




# Disconnect from the instrument
lockin.disconnect()

This code creates an instance of the SR865A driver and connects to the lock-in amplifier using the specified address (TCPIP::192.168.1.1::INSTR). You can then use the lockin object to interact with the instrument by calling its methods or accessing its parameters. Finally, you can disconnect from the instrument using the disconnect() method.
