540 Keysight N8262A Programming Guide
TRACe[1]|2[:DATA]? <character_data>
This query returns trace data from the specified channel. The trace resolution is
determined by <character_data>.
Data is returned in IEEE 488.2 arbitrary block program data format as follows:
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.
Syntax
#xyyy..yddd...................ddd<LF>
The number of y digits
Signifies the start of the block
The number of data bytes (d)
contained in the block.
Data bytes
Line feed character
signifies the end of the block
Example: if there are 12435 data bytes, y = 12435 and x = 5
TRACe data formatting is not affected by FORMat subsystem formatting.
