Connect to the QL335-P in Python

Read our guide for turning Python scripts into Flojoy nodes.

Flojoy

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 QL335-P Power Supply using Qcodes, you can use the following Python script:

from qcodes.instrument.visa import VisaInstrument
from qcodes.instrument_drivers.aimtti.AimTTi import AimTTi

# Create an instance of the AimTTi instrument
aim_tti = AimTTi("aim_tti", "TCPIP0::192.168.1.1::inst0::INSTR")

# Connect to the instrument
aim_tti.connect()

# Now you can use the instrument to perform operations
# For example, to get the voltage of channel 1
voltage = aim_tti.ch1.volt.get()

# You can also set the voltage of channel 1
aim_tti.ch1.volt.set(2.5)

# Disconnect from the instrument
aim_tti.disconnect()

Note that you need to replace "TCPIP0::192.168.1.1::inst0::INSTR" with the actual VISA resource address of your QL335-P Power Supply.
