Why are the pulse width and frequency of pulse not correct in my labview waveform?

Question

In the following image you see I set the pulse frequency to 50 Hz and pulse width to 2ms. The duty cycle computes to 10%, which is fed into a signal simulator.

enter image description here

When I execute the labview program the waveform I get is shown below:

enter image description here

This waveform is clearly not correct because pulse width and pulse frequency both appear to be about 10ms.

Following is the back panel wiring diagram.

My sampling rate is set to 200000Hz.

Why are my pulses not showing up correctly?

Was it helpful?

Solution

You have not added the duty cycle to the function generator. So it will use the default duty cycle (50 %).
