# 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](https://pyvisa.readthedocs.io/en/latest/) 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](https://pyvisa.readthedocs.io/projects/pyvisa-py/en/latest/)
VISA backend. However, in order to use any VISA functionality that
PyVISA-py does not implement, a third-party VISA backend such as
[TekVISA](https://www.tek.com/en/search?keywords=tekvisa&facets=_templatename%3dsoftware%26parsedsoftwaretype%3dDriver&sort=desc)
(>=4.2.0) or
[NI-VISA](https://www.ni.com/en-us/support/downloads/drivers/download.ni-visa.html)
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

```shell
pip install tm_devices
```

## Basic Usage

### Print Available VISA Devices

```console
$ list-visa-resources
[
  "TCPIP0::192.168.0.1::inst0::INSTR",
  "ASRL4::INSTR"
]
```

### Basic Script

```python
from tm_devices import DeviceManager

with DeviceManager() as device_manager:
    scope = device_manager.add_scope("192.168.0.1")
    scope.query("*IDN?")
    print(scope)
```
