3.9.1 How to do post processing
The post processing functions CALCulate1 and CALCulate2 comply with the front
panel functions MATH1 and MATH2 of the CombiScope instrument. They work
only in the digital mode. The use of the CALCulate functions is as follows:
1 Select the source for the post processing function.
2 Specify the settings of the post processing function.
3 Enable the post processing function.
4 Check the result of the post processing function.
3.9.1.1 Select the source for the post processing function.
Select the trace that is to be sourced into the CALCulate function by sending the
CALCulate<n>:FEED command.
Examples:
→
Send CALCulate2:FEED "CH3"
→
Send CALCulate:FEED "M2_1"
Empty traces may not be selected as input trace. A memory register 1 location
(M1_ j) may not be specified as the source (feed) for CALCulate1 and a memory
register 2 location (M2_ j) may not be the source (feed) for CALCulate2. After a
RST command, CH1 becomes the input trace for both CALculate functions.

Note: CH3 and CH4 cannot be selected as source for the PM33x0B
CombiScope instruments.
