ask help on the EAL SDK oscilloscope trigger mode

[yaxccha]

I try to implement the oscilloscope function based on the EAS sdk using c#, everything works fine until I met a question about the oscilloscope trigger

according to the EAL example, I try to set the automatic trigger mode, but come out with a problem, as attached

something like "Parameter: P-0-0026: Invalid operation data"

later, I try to use the executable demo in the example folder, it is the same problem.

But if I try to use the Indraworks DS, everythins works fine.

could anyone give me some advice on this topic? thanks

Hello,

are you using the latest version of EAL (2.3.0).

I was using the latest version and I do not get this error when using "automatic trigger" mode.

In your case something goes wrong with P-0-0026. Whats the value in this parameter?

I would suggest to do a "load basic parameter" to reset your drive settings.

Please send me a parameter backup if this issue still is present after a reset.

hi,

sorry for the late response.

1. I am using EAL(2.2.0), today I try to upgrade to 2.3, then I can only search device but cannot connect successfully.

2. I try to implement the automatic trigger mode according to the EAL document, when I come to the step of setting the trigger mode,

ealConnection.Oscilloscope.Trigger.Type = TriggerType.AutomaticTrigger;

but still failed with the error "Parameter: P-0-0026: Invalid operation data"

3. as for manual trigger, still come with the same error as point 2 when I try to set the trigger type

ealConnection.Oscilloscope.Trigger.Type = TriggerType.ManualTrigger;

then, I try to raise the trigger after start oscilloscope, as

   // Raise manual trigger
   ealConnection.Oscilloscope.RaiseTrigger();

but failed with the message "EAL.Exceptions.NotSupportedEALException: 'Axis:0 Parameter:P-0-0136 : IDN not supported'", and it seems that the parameter P-0-0136 doesn't exist in the device

attached is the par file of my device,

thanks in advance
