1.5.5.2 Instrument Mode: Dual Channel
Option -002 allows the selection of the Instrument Mode ‘Single Channel’, ‘Single
Channel with Marker’, ‘Dual Channel with Marker’, ‘Dual Channel’, or ‘Dual Channel
Duplicate’.
In Instrument mode ‘Dual Channel’ and ‘Dual Channel Duplicate’, no digital markers
are available.
Each channel can be enabled and disabled independently from other channels.
When sourcing one channel from extended memory and the other channel from
internal memory, the waveform sourced from extended memory is always sent at
channel 1.
