labview: biphasic square wave pulse starting at 0

[tchen]

I'm new to Labview and am trying to figure out how to generate biphasic square wave pulses that start & end at 0. I'm using a 33120A function generator / arb using GPIB. I've tried using the driver (the burst modulation and wave configuration VIs), but the pulses they give me start from the bottom of the square wave instead of from 0.

Any thoughts? Thanks.

You can generate your own waveform. 0, -1, -1, ... -1, +1, +1, ... +1, 0. Send that to the instrument, save it as Biphasic, and call it like the internal functions. I don't have one of the instruments or the documentation now, but I have done something like this in the past.

It works. Thanks!
