RIGOL Chapter 2 Command System
2-182 DSA800E Programming Guide
Note: As the PC software converts the binary data returned to ASCII character, the return value is
unrecognizable code when the PC software is used to execute the query command.
:TRACe:DATA? TRACE2
Remark:
[1] The format of the data block is "Data Block Header + Data Block"; wherein, the format of the data block
header is as follows.
The first figure (9) following # denotes the number of digits of the number in the data block header; this
number denotes the number of bytes of the data in this transmission (add 0 before the number when the
number of digits is less than 9). For example, the data block header is #9000000100 when 100 bytes of
data is transmitted.
[2] In the two examples here, 601 points are transmitted and the queries return 601 points. However, due
to the limited space, the succeeding data is omitted here. The return values in the above examples are
acquired when the trace stops sweeping.
