How to repeat finite pulse train with different frequency?

[gaingain]

Hi,all
 
 I attempt to generate following signal repeatedly:
<a href="mailto:***@100kHz+***@200kHz+***@300k" target="_blank">***@100kHz+***@200kHz+***@300k</a>&nbsp;+&nbsp;about 1ms interval
or
<a href="mailto:***@300kHz" target="_blank">***@300kHz</a> +&nbsp;about 1ms interval
&nbsp;
the quantity of the pulse must be accurate, and I don't know how to achieve it.
&nbsp;
My device is PCI 6013, software is LV 8.5, DAQmx
&nbsp;
How can I do that?
Many thanks.

Hi,
&nbsp;
The following VI is an example of how to generate the pulse train required. It would need to be tailored to your individual application but you can change the frequency as you like with the control on the front panel.
&nbsp;
I hope this is of assistance.
