Overall Status

NI-SCOPE Python API Status

Installation

As a prerequisite to using the niscope module, you must install the NI-SCOPE runtime on your system. Visit ni.com/downloads to download the driver runtime for your devices.

The nimi-python modules (i.e. for NI-SCOPE) can be installed with pip:

$ python -m pip install niscope

Or easy_install from setuptools:

$ python -m easy_install niscope

Usage

The following is a basic example of using the niscope module to open a session to a High Speed Digitizer and capture a single record of 1000 points.

import niscope
with niscope.Session("Dev1") as session:
    session.configure_vertical(range=1.0, coupling=niscope.VerticalCoupling.AC)
    session.configure_horizontal_timing(min_sample_rate=50000000, min_num_pts=1000, ref_position=50.0, num_records=1, enforce_realtime=True)
    with session.initiate():
        wfm, wfm_infos = session[args.channels].fetch(num_samples=args.length)
    print('Number of samples acquired: {:,}\n'.format(len(wfm)))

Additional examples for NI-SCOPE are located in src/niscope/examples/ directory.
