Notes: - If f=8 decimal, each trace sample is one byte (8 bits).
- If f=16 decimal, each trace sample is two bytes (16 bits), i.e., most
significant byte (msb) + least significant byte (lsb).
- The checksum is done over all trace sample data bytes by adding the
bytes one by one as follows: SUM = (SUM + byte N)MOD256

Response:
Limitations:
For the PM33x0B CombiScope instruments:
- CH3 and Mi_3 is not applicable.
- CH4 is the external trigger view channel, so:
• EXTernal is the alias for CH4.
• Mi_E is the alias for Mi_4.
COMMAND REFERENCE
Mi_n
n = 1 .. 4
i = 1 .. 8 (standard memory)
i = 1 .. 50 (extended memory)
Constant value:
- Range from -128 to +127 (1 byte trace
points).
- Range from -32768 to +32767 (2 byte
trace points).
The format of the block data is as follows:
NewLine code
checksum over all trace bytes
trace sample data bytes
trace data format byte
number of trace bytes (fbb...bbs)
number of digits of x..x
