When the source channel is the same as
the channel to which the calculation result
is recorded in the calculation formula, the
input waveform data of the source channel
is overwritten by the calculation result.
When using "MOV" or "SLI" for operators,
set the floating decimal point.

7.2 Waveform Calculation (MEM)
Waveform processing is possible only for the memory function.
Processing result are displayed as a waveform.
The maximum recording length allowing waveform processing calculation is
5000 divisions (20,000 divisions for 128 M words, 80,000 divisions for 512
M).
Use the A/B cursors to specify the processing range for the waveform data
within the maximum recording length .
The following operators can be used to define processing equations.
(1) Arithmetic operators (+, -, *, /)
(2) Absolute value (ABS)
(3) Exponent (EXP)
(4) Logarithm (LOG)
(5) Square root (SQR)
(6) Displacement average (MOV)
(7) Parallel displacement on time axis (SLI)
(8) 1st and 2nd differential (DIF, DIF2)
(9) 1st and 2nd integral (INT, INT2)
(10) Trigonometric functions (SIN, COS, TAN)
(11) Reverse trigonometric functions (ASIN, ACOS, ATAN)
