Manage connections and interactions with Test & Measurement devices.
Project description
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
TekVISA
(>=4.2.0) or
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)
