Connecting to Keithley S46 by Keithley in Python

Instrument Card

S46 Microwave Switch Systems are designed to simplify the automated switching needed to test a wide range of RF and telecommunication products and devices. The S46 can control 32 relay contacts in a package as small as a 2U high (3.5 in) full-rack enclosure.

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 Keithley S46 Switch using Qcodes, you can use the following Python script:

from qcodes.instrument_drivers.Keithley.KeithleyS46 import KeithleyS46

# Create an instance of the KeithleyS46 instrument
s46 = KeithleyS46("s46", "TCPIP::192.168.1.1::INSTR")

# Open a connection to the instrument
s46.connect()

# Print the available channels
print(s46.available_channels)

# Close channel 'A1'
s46.A1.set("close")

# Check if channel 'A1' is closed
print(s46.A1.is_closed())

# Open all channels
s46.open_all_channels()

# Close channel 'R2'
s46.R2.set("close")

# Check if channel 'R2' is closed
print(s46.R2.is_closed())

# Close the connection to the instrument
s46.disconnect()

This script creates an instance of the KeithleyS46 instrument, connects to it using the specified address (replace "TCPIP::192.168.1.1::INSTR" with the actual address of your instrument), and performs various operations on the switch channels. Finally, it disconnects from the instrument.
