7
5) Data (Unit:Byte)
The data will be permuted by 4 byte(32 bits) steadily.
Under the rule of permutation, the connected data from the same channel
(T1 and T2) will be apart by 4 Byte as DATA(a + 1) be the next data after
DATA(a).
As each byte represents the data of 8 channels, it will follow the sequence
from MSB to LSB.
In the above figure:
b7 of the DATA(a) is channel 7, b0 is channel 0
b7 of the DATA(b) is channel 15, b0 is channel 8
All the data will be circulated by 32bit(4Byte).
If the logic analyzer is 16 channels, the data of the two bytes from channel
16 to channel 31 will be kept in 0xFF.
For example:
Byte +0: ErrorCode, there is no error in the parameter setting.
Byte +1 ~ Byte +17: DateTime, storing the year, month, date, hour, minute,
second and millisecond by ASCII.
Byte +18 ~ Byte +1B: Trigger Address.
Byte +18 & Byte +19: High Word
Byte +1A & Byte +1B: Low Word
After combining the 4 byte, user will get the result 0x00000010, and it is also
the Trigger address.
If user set the Byte +0 to be the beginning address, it is in need to add
0x1C(the beginning offset of data) for the real trigger address.
Byte +1C to below: Data, each 4 byte will be one set.
Byte +1C, Byte +1D, Byte +1E, Byte +1F: The data of T1 from Channel 31
to Channel 0.
Byte +20, Byte +21, Byte +22, Byte +23: The data of T2 from Channel 31
to Channel 0.
