FWIW, the analog trigger output worked as a digital source for us using the counter class but seemed broken with the encoder class. Ref:

This counter command
Counter1.setUpSource(Trigger1, AnalogTriggerType.kRisingPulse);
seemed to work in setting the source. Would have liked a similar function for the encoder. E.g.
Encoder.setUpSource1(Trigger1, AnalogTriggerType.kRisingPulse);
Encoder.setUpSource2(Trigger2, AnalogTriggerType.kRisingPulse);
