PicoScope 3405D trigger problem

Postby Biturbo27 » Fri Nov 10, 2017 10:26 am

Hello everybody,

I want to trigger Channel A of my PicoScope 3405D at 2V at a range of 10V and a Sinus wave of 20 Hz Input Signal.
That's why I used the 'PicoScope3000aExampleStreaming.vi' and added the 'AdvancedtriggerSettings.vi'.
The threshold has to be in an adc-value, that's why I entered the value of 6554.
But the trigger doesn't work because if I run the program the oscilloscopes immediately begins to run. (See Pictures)

Can anyone please help me?

Hi Biturbo27,

In streaming mode, the device will begin to start collecting data irrespective of whether a trigger is set or not.

If the amount of data to be collected will be accommodated by the onboard buffer memory, then you can use a block mode capture, where the device will wait until the trigger condition is met before data is returned.

Could you tell me or send me an Example-VI how a block mode capture could look like?

Hi Biturbo27,

You can obtain block mode examples from the relevant sub-folder from the ps3000a folder in our GitHub repository.
