PicoScope6000 examples, trigger options doesnt work

Post by dtecnicjba » Mon Oct 08, 2018 11:14 am

Hi,
My device model is 6402C, I'm trying to use PicoScope6000ExampleBlock and I see that it does not respond to any value in the trigger options. I'm using channel A as a main channel and channel D as a trigger channel. All the settings are the default values instead the trigger settings where I've changed these ones
Trigger Source - Channel D
Auto Trigger Time - 0
Trigger Threshold - 1024
Trigger direction - Rising
Triger Delay (samples) - 0

I have also tested the other examples and the issue is the same.
I'm using labview 2014 64bit version.
Thanks in advanced for your help.
Àlex

Hi,
I have reproduced the issue. The reason why its not triggering is because the channel is not enabled.
So you will have to create a Channel Settings control for channel D.
In the top level vi (PicoScope6000ExampleBlock.vi) select the 'Channel D Settings' terminal on the
'PS6000 Settings' vi block and right click 'Create' -> 'Control'
This will add a 'Channel D Settings' control to the front panel, which you need to enable and set the voltage input range to at least work.

This looks like a bug with the function 'ps6000SetSimpleTrigger' not returning a error code, if the channel set is not enabled. I will investigate this further, and also the other scope dll's.

Hi Andrew

Great, If you activate ChannelD using a control for the ChannelD settings then ChannelD works fine as a trigger signal for ChannelA. I've used PicoScope6000ExampleRapidBlockBulk.vi

Thanks a lot.
