Hello all,

I need to generate a specified number of pulse signals using NI USB6211 and MATLAB daq toolbox. For example, 60 pulses are in need in about 1min of time. I'm now using code as follow. I use

DurationInSeconds
ch.Frequency

to control the number of pulse. But if the Frequency is high and Time is long, the number of pulse may not agree with my expect.

Can I generate a specified number of pulse signals with Counter output port in USB-6211 directly with MATLAB code?

I need precise control of number of the counter pulse and not too care about the time of pulse train.

test = daq.createSession('ni');
ch=addCounterOutputChannel(test,Device_ID,'ctr0','PulseGeneration');
ch.Frequency=1; % Palse per second
test.DurationInSeconds=60; 

Thanks for your help.
