Subject: DRS4 trigger, different polarity 

I need to synchronize two signals. These signals have a different polarity.

I can set triggers on different levels. But I can't set different polarity of triggers.

Now I can set (T1 and T2), I need to set (T1 and (not T2))

Is it possible?

 

           

d->SetTriggerLevel(-0.4,0.4,0.0,0.0,false);

d->EnableTrigger(1, 0);  // Enable trigger

d->SetTriggerSource(1<<8 | 1<<9);  // T1 and T2

 

file DRS.cpp:

int DRSBoard::SetTriggerLevel(double voltage1,double voltage2, double voltage3,double voltage4,bool negative)

{

      SetDAC(fDAC_TLEVEL1, voltage1/2 + 0.8);

      SetDAC(fDAC_TLEVEL2, voltage2/2 + 0.8);
