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->EnableTrigger(1, 0); // Enable trigger
d->SetTriggerSource(1<<8 | 1<<9); // T1 and T2
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);
There is no way to select different polarities, it is not implemented in the firmware. Like your digital oscilloscope has also only one polarity switch.
The only way to do it is to use a (passive) inverter, so that you have two signals of the same polarity. Something like this:
