Connect to the SR 850 in Python

PROTOCOLS > SCPI

Here is an example Python script that uses Instrumental to connect to a SR 850 Lock-in Amplifier:

import instrumental


# Connect to the SR 850 Lock-in Amplifier
sr850 = instrumental.SR850()


# Set the reference frequency to 1 kHz
sr850.set_reference_frequency(1e3)


# Get the reference frequency
ref_freq = sr850.get_reference_frequency()
print("Reference Frequency:", ref_freq)


# Set the sensitivity to 10 nV/fA
sr850.set_sensitivity(sr850.Sensitivity.x10nV_fA)


# Get the sensitivity
sensitivity = sr850.get_sensitivity()
print("Sensitivity:", sensitivity)


# Close the connection
sr850.close()

This script connects to the SR 850 Lock-in Amplifier, sets the reference frequency to 1 kHz, gets the reference frequency, sets the sensitivity to 10 nV/fA, gets the sensitivity, and then closes the connection.
