Connect to the Keithley 2700 in Python

PROTOCOLS > SCPI

from pymeasure.instruments.keithley import Keithley2700


# Connect to the Keithley 2700
keithley = Keithley2700("GPIB::1")


# Perform measurements or other operations with the instrument
# For example, you can read the state of the channels
state = keithley.get_state_of_channels([101, 102, 103])
print("State of channels 101, 102, 103:", state)


# Close specific channels
keithley.closed_channels = [101, 102, 103]


# Open all channels
keithley.open_all_channels()


# Close rows to columns on the 7709 connection matrix
keithley.close_rows_to_columns([1, 2], [1, 2])


# Open rows to columns on the 7709 connection matrix
keithley.open_rows_to_columns([1, 2], [1, 2])


# Perform system operations
keithley.beep(1000, 1)
keithley.triad(1000, 1)
keithley.reset()


# Display closed channels on the instrument's display
keithley.display_closed_channels()


# Disconnect from the instrument
keithley.disconnect()

This script connects to the Keithley 2700 using the GPIB address “GPIB::1”. It then performs some operations with the instrument, such as getting the state of channels 1 and 2, closing all channels, and finally disconnecting from the instrument.

Note that you may need to install the pymeasure package before running this script. You can install it using pip install pymeasure.
