Retriggerable Multirecord Acquisition HSDIO 6552

[engwei]

Hi,

I need to have multirecord acquisition since I only need to acquire data after 20M Sample.

I have refer to the acticle

http://digital.ni.com/public.nsf/allkb/FF921AD791E6037E86257142007F06BA

From my experiment, I m trying to acquire 10 samples, each at cycle0 and cycle600.

Data Active Event (PFI1) to Start Trigger (PFI2)

Marker0 to Advance Trigger (PXI backplane RTSI 0)

Script:

generate wfm0 marker0(0,600)

Waveform size = 700 lines.

Then, on the niHSDIO acquisition VI, 

number of record = 2

number of sample = 10

From the waveform indicator (showed in waveform table), I acquired from 

cycle0 to cycle9 (correct)

cycle 580 to 589 (incorrect)

Any suggestion about the error ? I expect the data acquired should be from cycle 600 to cycle 609.

Please help.. Thanks for your time.
