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
