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.
