shots mode on pico 5203

Hello everybody, could you please have a look at my .Vi software and see what is wrong. I am still trying to generate 30 cycle of 170khz sinusoidal signal of 2V pk to pk. For the moment this software is generating a 2V pk to pk, 170kHz sinusoidal signal, but the number of cycle is not good.

How long ( at least ) does the ps5000SigGenSoftwareControl must be set to "1" to make the trigger event detected?
