Connecting to Keysight N6705B by Keysight in Python

Instrument Card

The N6705B is a 4-slot mainframe that accepts up to 4 DC Power Modules, and up to 600 W total DC Power Module output power. The modules are ordered separately.

N6705B accepts the same modules as N6700 Modular Power System, with over 30 modules to choose from

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 Keysight N6705B Power Supply using Qcodes, you can use the following Python script:

from qcodes.instrument_drivers.Keysight.Keysight_N6705B import Keysight_N6705B

# Create an instance of the N6705B instrument
n6705b = Keysight_N6705B('n6705b', 'TCPIP0::192.168.1.1::inst0::INSTR')

# Connect to the instrument
n6705b.connect()

# Get the instrument identification
idn = n6705b.get_idn()
print(f"Instrument ID: {idn}")

# Set the voltage and current for channel 1
n6705b.ch1.source_voltage.set(3.0)
n6705b.ch1.source_current.set(0.5)

# Enable channel 1
n6705b.ch1.enable.set('on')

# Read the voltage and current from channel 1
voltage = n6705b.ch1.voltage.get()
current = n6705b.ch1.current.get()
print(f"Channel 1 - Voltage: {voltage} V, Current: {current} A")

print(f"Voltage: {voltage} V")
print(f"Current: {current} A")

# Disable channel 1
n6705b.ch1.enable('off')

# Close the connection to the instrument
n6705b.disconnect()

This script creates an instance of the Keysight_N6705B instrument, connects to it using the specified address (replace 'TCPIP0::192.168.1.1::inst0::INSTR' with the actual address of your instrument), gets the instrument identification, sets the voltage and current for channel 1, enables channel 1, reads the voltage and current from channel 1, and finally disconnects from the instrument.
