Recording the Measurement Waveform and Playback

[ouchie_85]

Hi,

Can anyone enlighten me on how to create the recording of waveform and playback version of it? Currently my vi's graph could display the waveforms measured but i wish to record the waveform and playback them again. Thanks!!

Hi ouchie_85,

how do you measure it? Do you read it from a hardware? You can use a state machine architecture with one case for record your data and one for playback them. You can store the data in a shift register.

Hope it helps.

Hi MikeS81,

I am using NI PCI-6723 to measure the voltage signals. I displayed the signals all together in the graph. What i wish to do is to record the waveforms on the graph and eventually replay is through playback for analysis purposes. Anyway, regarding the shift register, do you have any examples to illustrate your concept. Thanks bro!!

Hi ouchie_85,

here is a short example for you. It´s only a state machine you can insert queues to change the state with user events or ...!

Thanks Mike!! I shall have a look at it and try to change it to accomodate my requirements. Thanks
