Connect to the Keysight E8257D in Python

QCodes

To connect to a Keysight E8257D RF Signal Generator using Qcodes, you can use the following Python script:

import qcodes as qc
from qcodes.instrument_drivers.Keysight.Keysight_E8257D import Keysight_E8257D

# Create an instance of the instrument
signal_generator = Keysight_E8257D("signal_generator", "TCPIP0::192.168.1.1::INSTR")

# Connect to the instrument
signal_generator.connect()

# Print the instrument ID
print("Instrument ID:", signal_generator.IDN())

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

# Set the power to -10 dBm
signal_generator.power(-10)

# Enable the output
signal_generator.output_enabled(True)

# Disable the output after 1 second
qc.sleep(1)
signal_generator.output_enabled(False)

# Disconnect from the instrument
signal_generator.disconnect()

This script creates an instance of the Keysight_E8257D instrument class from the Qcodes driver. It then connects to the instrument using the specified address (TCPIP0::192.168.1.1::INSTR). The instrument ID is printed using the IDN() method.

The frequency is set to 1 GHz using the frequency() method, and the power is set to -10 dBm using the power() method. The output is enabled using the output_enabled() method.

After a delay of 1 second, the output is disabled by setting output_enabled to False.

Finally, the script disconnects from the instrument using the disconnect() method.
