Function definition
(cont'd)
Files Contains the list of the functions (.FCT) saved by the user, along with two
predefined files.
By selecting the name of the function with the stylus (function name in blue),
you can transfer the definition of the function into the 2 lines provided for that
purpose.
The scroll bar can be used to scroll through the list of memorized functions.
The function can be modified with the table of usable characters, associating
the ch1 and ch2 traces.
This menu also contains two predefined functions.
C1MULC2.FCT and SQUARE.FCT
C1MULC2 .FCT Product of 2 traces with scaling:
math3 = ch1*ch2/divv(4) = C1MULC2.FCT
The factor divv(4) is used to optimize the display as long as the source signals
have sufficient dynamics (> 6 divisions) and no overshooting.
SQUARE .FCT Definition of a square signal using the first 4 harmonics of a Fourier series
development.
math3 = SQUARE.FCT
math3 = (sin(pi*t/divh(2)) + sin(3*pi*t/divh(2))/3 + sin(5*pi*t/divh(2))/5
+ sin(7*pi*t/divh(2))/7)*divv(4)
