# instro
> An open-source, vendor-agnostic Python library for interfacing with test equipment.
```python theme={null}
from instro.daq.drivers.labjack import LabJackTSeriesDriver
# from instro.daq.drivers.ni import NIDAQDriver
from instro.daq import InstroDAQ
from instro.daq.types import Direction
daq = InstroDAQ(
name = "myDAQ",
driver = LabJackTSeriesDriver(device_id="1234")
#driver = NIDAQDriver(device_id="Dev1") # swap drivers, same code
)
daq.open()
daq.configure_analog_channel(
direction=Direction.INPUT, physical_channel="AIN0", alias="ch_0", range_min=0, range_max=5
)
measurement = daq.read_analog()
```
### Purpose
The python ecosystem for test and measurement is fragmented and redundant. `instro` is an [open-source](https://github.com/nominal-io/instro) Python library for interacting with test equipment from one unified, typed API. It provides virtual instruments that are **vendor-agnostic**. Instro instruments use `Publishers` to automatically stream data to a file, [Nominal](https://nominal.io), or a destination of your own.
