1 0 multiple transitions in interval ending with low
For individual digital channels (such as CH<x>_D<n> ), :DATa:WIDth 2 provides
the 2-bit transition data with the upper 14 bits zero. :DATa:WIDth 1 provides only
the state in the LSB with the upper 7 bits all zero.
For CH<x>_DAll sources, :DATa:WIDth 2 provides the 2-bit transition data
for each of the 8 constituent channels with the D7 bit represented in the 2 most
signi
fi cant bits, D6 in the next 2, and so on. :DATa:WIDth 1 provides the states
of each of the 8 constituent channels with D7 represented in the most signi fi cant
bit and D0 in the least signi fi cant bit.
Depending on the sample rate, multi-transition data may not be available and
:CURVe? queries for digital channels with :DATa:WIDth 2 may result in a
warning event "Execution warning: Multi-transition data not available". In this
case, the transition data returned will be 0 0 or 0 1.
For MATH sources, only 8-byte double precision fl oating point data is returned in
:CURVe? queries.

<Block>
is the waveform data in binary format. The waveform is formatted as:
#<x><yyy><data><newline>, where:
<x> is the number of y bytes. For example, if <yyy>=500, then <x>=3)
NOTE.
<x> is hexadecimal format. The letters A-F denote several y bytes
between 10 and 15 digits.
<yyy> is the number of bytes to transfer. If width is 1, then all bytes on
the bus are single data points. If width is 2, then all bytes on the bus are
2-byte pairs. If width is 4, then all bytes on the bus are 4-byte pairs. Use the
command to set the width.
