New to LabView-Sampling and Sampling n Holding procedures

[Peponas]

Hello

I'm new to LabView and I use this software to simulate some projects in the university.I want to simulate Sampling of a Sin wave but after trying a lot of procedures (like multiplying pulse signal with wave signal) I finally discover that I cant.Can somebody please propose a proper .vi file that can do my work?The sampling is physical sampling with the following characteristics

sampling frequency:4kHz

pulse duration: 25μsec

Sin amplitude:2V

Sin frequency: 1kHz

I know that my question is a fool one but I'm interested in knowing the basics first so my work can be done.Thanks in advance

You should have a look at the Basic Function Generator VI, you can set the amplitude, frequency of the sine and frequency and duration (in samples) of the waveform.

 One call should give you all.

One question though, 4 kHz is 250  μsec per sample. So if the signal is only 25 μsec wide you will not be able to sample.
