tm_devices: Test & Measurement Device Management

tm_devices is a device management package which allows for better control and usage of Test & Measurement devices in python scripts. This is accomplished by using the PyVISA package to manage connections and communication with devices. tm_devices gives users access to a much higher level abstraction of device control by providing access to device drivers with a complete Python API.

Dependencies

tm_devices can be used without any external (non-python) dependencies on any operating system thanks to the PyVISA-py VISA backend. However, in order to use any VISA functionality that PyVISA-py does not implement, a third-party VISA backend such as NI-VISA can be installed. tm_devices will use an available VISA backend if one is found and will fall back to using PyVISA-py if no other VISA backends are installed.

Installation

pip install tm_devices

Basic Usage

Print Available VISA Devices

$ list-visa-resources
[
  "TCPIP0::192.168.0.100::inst0::INSTR",
  "ASRL4::INSTR"
]

Basic Script

from tm_devices import DeviceManager

with DeviceManager() as device_manager:
    scope = device_manager.add_scope("192.168.0.100")
    scope.query("*IDN?")
    print(scope)
