1) Arithmetic
(Off/CH1+CH2/CH1-CH2/CH2-CH1/CH1 Invert/CH2 Invert)
Off : This cancels the arithmatic function.
Ch1 + Ch2 : This displays a waveform which adds signals of two channels.
Ch1 - Ch2 : This displays a waveform which subtracts Ch2 from Ch1.
Ch2 - Ch1 : This displays a waveform which subtracts Ch1 from Ch2.
Ch1 Invert : This displays an inversed waveform signal of Ch1.
Ch2 Invert : This displays an inversed waveform signal of Ch2.
Displaying a math waveform automatically removes the display of channels used to create the math waveform. Math
operations are turned off if a channel used in the operation is turned on.
2) Advanced Functions (Off/Pass-Fail/FFT)
Off : This cancels the Advanced functions.
Pass-Fail : User sets the judgement range of Pass-Fail displayed on the screen and compares it with acquired
waveforms. When this menu is selected, submenu On, Off, Ch1, Ch2 and Edit are displayed. This
function is automatically canceled when XY format display is operated, AUTOSET is operated,
Measure menu is operated, ROLL mode is operated, Arithmatic function is operated or Cursor function
is operated.
Source (Ch1/Ch2)
CH1 : Be selected judgement area as "to be edited signal source" and "to be compared signal source".
CH2 : Be selected judgement area as " to be edited signal source" and "to be compared signal source".
Zone Edit (Off/Upper Side/Lower Side/Done)
Off : This clears all judgement area currently set on the screen and cancels comparing function. But the
data in the memory are not cleared.
Upper Side : This decides to be edited portion from upper portion of the waveform. The edited portion be adjusted
to use function knob. And it only moves to the upper side of the reference waveform. This mode don't
use the others menu except the function knob.
Addition, subtraction and inversion arithmetic of
the two channels are able to be carried out to
Ch1 or Ch2 by Arithmatic.
