In this case, th
e Digital Collection data returned will be 32-bit packed integers,
where each point is represented as follows. Note that the trigger state bit described
below is only available when ACQuire:MAGnivu is 1 (on).

8ByteData. When the data width is set to 8 bytes, the Digital Collection
represents
the transition state information for digital channels D0 – D15 and
the digital representations of analog Channels 1 – 4.
The "transition state" refers to MSB and LSB bits which together represent the
state of the digital channel during the sampling period, as fol
lows:
MSB LSB Transition/State
0 0 Low
01High
10
Single transition
1 1 Multiple transitions
If the width specified using the DATa:WIDth command is 8 bytes, the Digital
Collection data returned will be 64-bit packed integers, where each point is
represented as follows:
