Fluke PM-3370B Requests channel 1 trace, Reads channel 1 trace, Queries peak-to-peak, Value = 4 +

4 - 112	COMMAND REFERENCE
Send → TRACe? CH1	Requests channel 1 trace.
Read ← <block_data>	Reads channel 1 trace.
Determine nr.of.samples from <block_data>.
Send → SENSe:VOLTage:RANGe:PTPeak?	Queries peak-to-peak.
Read ← <peak-to-peak>	Reads peak-to-peak.
Send → SENSe:VOLTage:RANGe:OFFSet?	Queries offset.
Read ← <offset>	Reads offset.

IF (sample is 1 byte) THEN FOR i = 1 TO nr.of.samples

Determine trace(i) value from <block_data>.

IF trace(i) > 127 THEN trace(i) = trace(i) - 256 sample(i) = trace(i) / 200 * <peak-to-peak> - <offset> NEXT i

ELSE (sample is 2 bytes) FOR i = 1 TO nr.of.samples

Determine msb of trace(i) value from <block_data>. Determine lsb of trace(i) value from <block_data>. IF msb < 128 THEN trace(i) = msb * 256 + lsb ELSE trace(i) = (msb - 256) * 256 + lsb

sample(i) = trace(i) / 51200 * <peak-to-peak> - <offset> NEXT i

END IF

Example 2:
Send → FORMat INTeger,8	Number of trace point bits becomes 8.
Send → TRACe M1_2,5	All trace points of trace 2 of memory
	register 1 are set to the value 00000101 (bit
Send → FORMat INTeger,16	value = 4 + 1).
	Number of trace point bits becomes 16.
Send → TRACe M2_3,1025	All trace points of trace 3 of memory
	register 2 are set to the value
	0000010000000001 (bit value = 1024 + 1).

Front panel compliance:

The TRACe command is the remote equivalent of the front panel SAVE ACQ TO MEMORY option of the SAVE menu. The TRACe? query is the remote equivalent of the front panel RECALL REGISTER MEMORY option of the SAVE menu.
