PyNiScope

provides a Python package niscope that wraps the NI-SCOPE driver software for Python using ctypes. The package is tested with NI-SCOPE library version 3.3.2 using PCI-5122 cards Windows XP, and PXI-5114 on Windows 7.

Basic usage

Example:

import matplotlib.pyplot as plt
import niscope
from niscope.niScopeTypes import TRIGGER_SOURCE, SLOPE

scope = niscope.Scope("dev1")
scope.ConfigureHorizontalTiming()
scope.ConfigureVertical()
scope.ConfigureTrigger("Edge",
                       triggerSource=TRIGGER_SOURCE.EXTERNAL,
                       level=2.5,
                       slope=SLOPE.POSITIVE,
                       holdoff=0,
                       delay=0)
scope.InitiateAcquisition()
raw_input("Enter")
data = scope.Fetch()
scope.close()
plt.plot(data)
plt.show()

Requirements

The national instruments NI-Scope drivers are required. If you do not have a physical NI scope, it is possible to test pyniscope by installing a simulated instrument in the NI Measurement & Automation Explorer. [Search ni.com for NI-SCOPE](http://search.ni.com/nisearch/app/main/p/bot/no/ap/tech/lang/en/pg/1/sn/ssnav:dwl/q/ni-scope/). Pyniscope was origionaly tested on linux with NI-SCOPE 3.1, NI-KAL 2.1, and NI-VISA 5.0.
