Hi,
I need to generate 5 TTL pulses of 5MHz frequency, at every 10ms. Like 5 monoshots, repeated at 100Hz. I am using the PXI6602 card to do this. I started with the continous pulse gen NI TIO example and then used gated counters to get the required wave.
I am using traditional DAQ.
Now I have a 5 pulses @5MHz followed by 0 level for the next 10ms.And then again 5 pulses and so on.
I used counter0(at 100Hz) to genrate a gating signal that I routed to the gate of ctr1 operating in continous mode at 5MHz to get the pulses.
Now, I need another pulse in sync with my first burst, but I need a 5V level in between the bursts.(ie for 10ms).I send the gating signal to another counter(ctr2) operating at 5MHz and tried changing the output polarity to negative.Now I have 5V between my bursts, but the two bursts from ctr1 and ctr2 are 180 out of phase.I need the two pulse bursts to be in-phase, but during the idle period one signal should be 0v while the other should be 5V.
Is there any way to change the "idle state" voltage level of the counters without changing the output polarity?
please help!!I I need these two waveforms to proceed with my project!!
PS: sorry for thread duplication. I have posted the questions to the counter/timer board also.Please reply!!
