Data format description of OTA waveform file
OTA file consists of two parts: the file header and the data. The file header represents the
parameter of file data, which is expressed in "parameter name + value". Each parameter name is a
case-sensitive string of 4 bytes. The parameter value is at least 4 bytes.
1.Format description of the file header:
1) HEAD
Parameter name Meaning Value Comment
HEAD Header size 4 bytes int
2) TYPE
Parameter name Meaning Value Comment
TYPE Model 12 bytes char
3) BYTE
Parameter name

BYTE Data length in bit 4 bytes int
4) SIZE
Parameter name Meaning Value Comment
SIZE File size 4 bytes int Used to check the file
integrity
5) VOLT
Parameter name Meaning Value Comment
VOLT Voltage division,
divided by 400 is
ADC resolution.
(When the source is
CH1&CH2, it is CH1
voltage division.)
4 bytes float The value indicates voltage
(the unit is mV), such as 200
mV.
6) SAMP
Parameter name Meaning Value Comment
SAMP Sample rate 4 bytes float The unit is Sa/s.
7) ADCB
Parameter name Meaning Value Comment
ADCB ADC bit, ADC 4 bytes int 8-bit or 12-bit
