dal005 - Schottky System. Strange behavior when using downsampling mode #73

As soon as a downsampling factor is used, the scope does not trigger properly any more.

Known good configuration: Trigger only on CMD_BEAM_INJECTION, disable trigger on CMD_BEAM_EXTRACTION and CMD_START_ENERGY_RAMP

With downsampling mode, triggers are only received, if no events are disabled (Only CMD_BEAM_EXTRACTION) . As soon as any event is disabled, no data is received at all.

That strange behavior continues even if "downsampling_factor = 1" is picked.

(Doing downsampling in the same way than for dal025, which uses a factor of 8 .. seems to work fine there)

Added "external" label, since most likely can be reproduced on stand-alone ps3000 without using FESA (by using a realistic trigger event-schedule)
