Lower Side :
This decides to be edited portion from lower portion of the waveform. The edited portion be adjusted to
use function knob. And it only moves to the lower side of the reference waveform. This mode don't use
the others menu except the function knob.
Done :
This performs a operation of comparing judgement area set by user with acquired waveform. When
acquired waveform is in judgement area, RUN is maintained, and when acquired waveform is get out
of the judgement area, STOP is displayed and waveform is stopped. When comparing function is
necessary again, maintain RUN by pressing RUN/STOP switch. The waveform is regenerated when
selecting On after setting Off
Off/On
Off :
Selects not to activate PASS-FAIL function.
On :
Selects to activate PASS-FAIL function.
FFT
Source (CH1/CH2)
CH1 :
CH1 is selected source as to be transformed FFT.
CH2 :
CH2 is selected source as to be transformed FFT.
Window (Rectangle/Hamming/Hanning)
Rectangle :
Transforms to rectangular mode.
Hamming :
Transforms to hamming mode.
Hanning :
Transforms to hanning mode.
Execute/Calculating
Execute :
Calculates the FFT. After calculate, display of the waveform is stopped.
Calculating :
Displays the status of calculating.

This allows acquired waveforms to be converted into
frequency-domain traces, revealing valuable spectral
information that would otherwise be impossible to
detect on a time-domain record.
TIME/DIV.
A time axis range can be set by the TIME/DIV knob. When the knob turn to 5s,
TIME/DIV is slow in and turn to 2ns, TIME/DIV is fast in.
