CALCulate:MATH? (@<computed_ch_list>)
A computed channel performs mathematical operation on the readings from measurement channels, or other com-
puted channels list. Selects type of < expression > to specify the mathematical operation, and the operand channels
that are used for computing.
Only supported on computed channels (channels 401 through 420).

Basic math examples:
Selects math operation (add), and operand channels (channel 101 and 102) that are used for computing in channel
401:
CALC:MATH (@101+@102),(@401)
Typical response: "(@101+@102)"
In this example, you can replace the (@101+@102) with (@101-@102), (@101*@102), and (@101/@102) for
subtract, multiply, and divide operations.
Selects math operation (power), and operand channels (channel 101) that are used for computing in channel 401:
CALC:MATH (power(@101, 2)),(@401)
Typical response: "(power(@101, 2))"
