TRACe[:DATA]
Syntax:
TRACe[:DATA] <destination_trace> , <NRf> | <definite_block>
Alias:
DATA[:DATA] <destination_trace> , <NRf> | <definite_block>
<destination_trace> Mi_n
n = 1 .. 4
i = 1 .. 8 (standard memory)
i = 1 .. 50 (extended memory)
<NRf> Constant value:
- Range from -128 to +127 (1 byte trace
points).
- Range from -32768 to +32767 (2 byte
trace points).
<definite_block> The format of the block data is as follows:
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
Query form:
TRACe[:DATA]? <source_trace>
<source_trace> CHn | Mi_n
n = 1 .. 4
i = 1 .. 8 (standard memory)
i = 1 .. 50 (extended memory)
Response:
<definite_block>
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.
