PyVISA remote server and client in order to address your remote "local" hardware as it would be plugged in locally.

PyVISA-proxy

This plugin should extend PyVISA's funtionality mainly in order to address local hardware which is attached to a remote node, e.g. USB or GPIB. In the end, you can decouple your VISA instrument hosting where you need bare metal nodes and the test script runner.

Getting started

Installation

Using pip:

pip install pyvisa-proxy

Server

In order to make devices remotely available, just run the PyVISA-remote server on your node. The server will open new VISA resources per request. Just run

python -m pyivsa_proxy --port 5000

in order to host your "local" connections. Use any available port for network sharing.

Client

Use a client like a normal PyVISA class. The calls will be forwarded by reflection to the server. In order to get started, use the following snippet in your code.

import pyvisa

rm = pyvisa.ResourceManager("YourProxyServerIp:YourProxyServerPort@proxy")
instr = rm.open_resource(resource="GPIB0::1::INSTR")
print(instr.query("*IDN?"))
