Synchronous pulse trains generation by PCI 6602 counter

[Irena]

Hi!

I need to generate two different pulse trains with same trigger from PCI 6602 counter with simultaneous rising of first pulses.

I used the Triggered Pulse Train Generation mode (Traditional NIDAQ & LV7.1). Generally it's working.
The problem is, that the both of trains begins from low part of period, and it's impossible to get two simultaneous rise slopes (of first pulses). Train of higher frequency begins few periods before second train pulse rises. Changing of polarity of signals doesn't helps.

Do somebody knows way to begin the Pulse generation from first rising of the pulse period?

Irena,

Is programming in NI-DAQmx an option? Counter operations are much more straightforward in the new driver. The LabVIEW shipping example, Gen Dig Pulse Train-Continuous-Dig Start.vi should accomplish just this, provided the two counter operations use the same trigger.

Hope this helps,
