Connecting to HDO4000A by Teledyne in Python

Instrument Card

HDO4000A oscilloscopes have 4 analog input channels, 12-bit resolution using Teledyne LeCroy’s HD4096 high definition technology, up to 1 GHz of bandwidth and a compact form factor with a large 12.1” multi-touch display. They are ideal for debug and troubleshooting of power electronics designs, digital power management or power integrity analysis, automotive electronics systems, and deeply embedded or mechatronic designs.

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.

InstrumentKit

To connect to a HDO4000A Oscilloscope using Instrumentkit, you can use the following code:

import instrumentkit as ik

# Connect to the oscilloscope
oscilloscope = ik.teledyne.MAUI.open_visa("TCPIP0::192.168.0.10::INSTR")

# Perform operations on the oscilloscope
oscilloscope.run()
print(oscilloscope.trigger_state)

# Close the connection
oscilloscope.close()

This code imports the instrumentkit module and uses the open_visa function from the ik.teledyne.MAUI module to connect to the oscilloscope. The IP address “192.168.0.10” is used as an example, and you should replace it with the actual IP address of your oscilloscope.

Once connected, you can perform operations on the oscilloscope, such as starting the trigger in automatic mode and printing the trigger state. Finally, you can close the connection to the oscilloscope using the close method.

Note: This code assumes that you have already installed the necessary dependencies for Instrumentkit and have the correct VISA backend installed.
