The return format is related to the return format of the currently selected waveform
data.
WORD or BYTE format: The read data format is TMC header + waveform data points
+ end identifier. The TMC header is in the form of #NXXXXXX. Wherein, # is the
identifier, N indicates the N bytes following it. The length of the waveform data
points is in the form of ASCII. The end identifier is used to indicate the ending of
communication. For example, the data read for one time is #9000001000XXXX. It
indicates that 9 bytes are used to describe the data length. 000001000 indicates the
length of waveform data, i.g. 1000 bytes.
ASCii: The query returns the actual voltage value of each waveform point in scientific
notation; and the voltage values are separated by commas.
Note: When the channel source of waveform data reading is set to a digital channel,
the query command always returns the waveform data in BYTE format. If the
command reads the screen waveform data, it returns the signal status of the
currently selected channel source. One waveform point occupies 1 byte (8 bits). If
the command reads the memory waveform data, it returns the signal status of the
channel group where the currently selected channel sources reside. 1 byte
represents the status of one group of digital signals.
When the waveform data in the internal memory are read in batches, the waveform
data returned each time might be the data in one area of the internal memory. In
"WORD" or "BYTE" return format, each returned data in blocks contain the TMC data
block header. Waveform data in two adjacent data blocks are consecutive.
The returned value is related to the current data reading mode:
In NORMal mode, XINCrement = TimeScale/100.
In RAW mode, XINCrement = 1/SampleRate.
In MAX mode, XINCrement = TimeScale/100 when the oscilloscope is in the Run
state; XINCrement = 1/SampleRate when the oscilloscope is in the Stop state.
The unit is related to the current channel source.
The returned value is related to the current data reading mode:
Sets the waveform reading mode to RAW.
Sets the return format of the waveform data
to BYTE.
Reads the number of memory waveform
points to 10000.
Reads the waveform data from the internal
memory.
