Trace:data? <Character_Data>[,Hres] - Keysight 8990B Programming Manual

TRACe:DATA? <character_data>[,HRES]
This query returns the current trace data of the specified source. The data is
returned as a definite-length binary block of floating point numbers.
#xyyy..yddd...................ddd<LF>
Example: if there are 12435 data bytes, y = 12435 and x = 5
Each point in the trace is represented as an IEEE-754 32-bit floating point
number, made up of four bytes in the data block. The MS byte is transmitted first.
Each complete block is terminated by a line feed.
[,HRES] is an optional parameter which returns high-resolution data when
specified.
– [,HRES] is only applicable for channels 1 and 4.
NOTE
– When the acquisition is stopped or paused, using the [,HRES] parameter is
– This command is only applicable for timebase scale below 2 ms.
