5911 acquisiton delay

[David19]

Dear Sir/Madam,

I've got some problem about the 5911 Digitaizer Card Acquisiton Delay time .

How to measure the time from the Trigger siganl to the first point of Acquire ?? Do LabView Support this function??

Beside what is the different betwenn the Acquisiton Start Time and relativeInitalX ??? Plz

Plz help me ?? Thx


With Regards

David

Hi David,
Both the Acquisition Start Time and relativeInitialX provide the same information: the time in seconds from the trigger to the first sample in the acquired waveform.

The only difference is that the relativeInitialX is an output from several read and fetch VIs (ie, niScope Read Cluster) whereas the Acquisition Start Time is a property in a Property Node which can either be read from or written to. Thus you can set the Acquisition Start Time through the property node.

Hope that helps, have a great day!

One more thing,
Yes LabVIEW does support this function. The VIs and property nodes I referred to above are all in LabVIEW.
