Dos-2090

Hello

I've bought one of  PC based digital oscilloscope (dos-2090) . And I work with labview software and I need to trigger the two-channel Simultaneously. But in the labview example, only two states 0 and 1 is for the trigger .
This is while in Basic software Trigger Mode is  0 and 1, 2 and 3 that state 2 is alt  Trigger Please help me in this case

If the driver VIs do not provide the functionality you want, then you will have to write your own VI by reading the programming manual for this instrument.

Thank you for lead me.

I need to trigger the two-channel Simultaneously because I want to find phase of two signal

I suggest your read the manual to see if it is possible for this cheap instrument.   http://www.hantek.com.cn/english/produce_list.asp?unid=62

Ok I read manual.

There are two manual ,one of them is about labview and another is about V . In them are two different description

In labview --> Trigger:

If value is 0, it is Ch1 trigger.

If value is 1, it is Ch2 trigger.

In VB -->Trigger Source: index of the trigger source (CH1 trigger is 0, CH2 trigger is 1, ALT trigger is 2, EXT trigger is 3)

What does the trigger source have to do with your problem of acquiring two channels? The trigger source is irrelevant to whether you capture one or two channels. Explain exactly what you think the problem is?

You marked the post as solved. If that was a mistake, change it (Click on the Options button).

Thank you

The main software of the oscilloscope  By changing the Trigger Source Trigger will be two channels simultaneously However,  in the labview example  can not be done
