Title: Hantek 6022 Trigger limitations? [Print this page] Author: andreas_electro Time: 2017-8-17 17:11 Title: Hantek 6022 Trigger limitations? Hello, just new to this device I try to measure a 1MHz pulse signal.
The settings are 2us/div 48MHz sampling, single shot rising edge 50mV level.
Somtimes I see nearly 4 pulses:
The trigger point seems to be not on the screen at all, I see it when increasing the pulse distance.
Only the first negative pulse on the plot keeps it's position.
The positive Edge triggered is left of the screen and I am not able to see any pretrigger data!
Is this a known bug?
If this device should be useful for unknown signals I strongly recommend to show the trigger point in the plot! For the HW it would be better if a delay in the data path compensates the delay of the trigger unit.
Any further suggestions?
Regards, Andreas

Sir, sorry to reply you so late.
This product is software trigger.
The trigger position is fixed on the software display, that you can see.
But the trigger point is not fixed. And the total width of them is fixed. So the widths of pre triggering and post triggering are variable.
The trigger point is not clearly indicated.
