Return Format
The data returned contains 2 parts: the TMC data description header and the
waveform data.
#900000ddddXXXX...
Wherein, dddd denotes the number of the effective waveform points in the data
stream.
When reading the internal memory data, the waveform data returned each time
might be the data block in one area of the buffer. Each data block has a TMC
description header similar to #9XXXXXXXXX, wherein XXXXXXXXX denotes the
number of the waveform points in this data block. Waveform data in two adjacent
data blocks are consecutive.
The waveform data read can be converted to the voltage of each point of the
waveform on the screen according to the method below.
The figure below shows the waveform data read. First, select "View as hexadecimal
only" from the dropdown list at the right of Buffer; at this point, the waveform data
read is displayed in hexadecimal format; the first 11 figures denote the number of
bytes that the "Denoter" holds in the internal memory; the figures following are the
waveform data on the screen and users can convert the waveform data read to the
voltage of each point of the waveform on the screen using the formula (ox63 -
vertical reference position in Y direction) × VerticalScale-OFFSet. For the vertical
reference position in Y direction, refer to the
:WAVeform:YREFerence? command, for
the VerticalScale, refer to the
:CHANnel<n>:SCALe command and for the OFFSet,
refer to the
:CHANNel<n>:OFFSet command.
