Setting Constants
The selectable range is from –9.9999E+30 to 9.9999E+30.
Setting the Threshold Level of Binary Computation
With binary computation, the specified waveform (CH1 to CH16, Math1 to Math7) is
converted to a digital waveform of 0 and 1 with respect to the threshold level (Upper,
Lower).
1
0
Upper threshold level
Lower threshold level
The selectable range for the threshold level varies depending on the specified waveform
as shown below.
CH waveforms:
10 divisions within the display screen (resolution is (V/div setting)/100
when observing voltage and 0.1
°
C when observing temperature).
Math1 waveform:
10 divisions within the screen (resolution is 0.01 division).
Setting the FFT: FFT Points/FFT Window
For a description of the FFT, refer to points, FFT frequency band, and window in Section
10.3, “Performing Power Spectrum Computation (FFT).”
For details on digital filters and the FFT, refer to Appendix 5.
Phase Shift
The phase of a specified waveform is shifted. The amount of shift is specified in the
phase shift setup menu.
The selectable range is Time/div*5 (the resolution is 1/(sample rate)).
Linear Scaling
When performing computation on a channel that has linear scaling set, the computation
is performed on the scaled value.
Notes When Performing Computation
Computation is not performed again when you change Start Point or End Point while
computation is stopped. Be sure to press the Exec soft key to perform the computation
again. Otherwise, the waveform will not be displayed correctly when the screen is
redrawn.
Note
While computation is in execution,
is displayed at the upper left corner of the screen.
