Generate Sine Wave Output with USB6216 Module

[nicowagner98]

Hello everyone,

I tried to generate a sine wave output on an analog output from my NI-USB 6216 module with nidaqmx. This code is what I have done but it doesn't work...

import nidaqmx
import numpy as np
from nidaqmx.stream_writers import AnalogSingleChannelWriter

SamplesPerSignal = 1000
SignalFrequency = 1000
NumberOfCycles = 100000000
Amplitude=2
w=2*np.pi*SamplesPerSignal
Sample = np.linspace(0,SamplesPerSignal,num=SamplesPerSignal)
Signal= np.sin(Sample*w)*Amplitude

with nidaqmx.Task() as task:
    task.ao_channels.add_ao_voltage_chan("Dev1/ao0")
    task.timing.cfg_samp_clk_timing(rate=SignalFrequency*SamplesPerSignal,sample_mode=nidaqmx.constants.AcquisitionType.CONTINUOUS,samps_per_chan=SamplesPerSignal*NumberOfCycles)
    SignalStreamer = nidaqmx.stream_writers.AnalogSingleChannelWriter(task.out_stream, auto_start=True)
    SignalStreamer.write_many_sample(Signal)
