Waveform Analysis
Waveform Computation
Arithmetic, binarization, phase shifting (display the waveform with its phase shifted), frequency, period, moving
average (2, 4, 8, or 10 points), and RMS can be computed.
FFT
The power spectrum of the input waveform can be displayed in the FFT window. Up to two FFT waveforms can
be displayed.
X-Y Waveform
You can observe the correlation between two waveform signal levels by displaying one signal level on the X-axis
(horizontal axis) and a second signal level on the Y-axis (vertical axis). Because multiple X-Y waveforms can
be displayed, it is easy to compare the relationships between phases. You can use this feature to evaluate DC
motors using Lissajous waveforms.
Harmonic Analysis
You can analyze the 1st to the 40th harmonics of rms values (voltage, current) and active power.
GO/NO-GO Determination (Scope mode only)
This feature is useful for signal testing on production lines and for tracking down abnormal phenomena. The
instrument determines whether the waveform enters the specified range. When the instrument returns a GO (or
NO-GO) result, specified actions are performed.
The instrument returns GO/NO-GO results based on whether waveforms leave or enter the zone that you create
using a base waveform.
Waveform Zoom (Scope mode only)
You can magnify displayed waveforms along the time axis. In scope mode, the zoomed waveforms of two
locations can be displayed simultaneously (the dual zoom feature). This feature is useful when you set a long
acquisition time and want to observe a portion of the waveform closely.
Waveform Display Position and Zoom (Recorder mode only)
You can magnify displayed waveforms along the time axis. In recorder mode, the zoomed waveform of one
locations can be displayed.
Searching Waveforms
You can search the displayed waveforms for locations that match the specified conditions. You can zoom-in on
the detected locations.
History Waveform Display (Scope mode only)
Acquisition memory stores waveforms that are displayed on the screen and waveform data that have been
acquired in the past. The history feature allows you to any single waveform or display all waveforms (and
highlight only the specified waveform).
You can also list the timestamps (the times at the time references) of all history waveforms.
Position Information (GPS)
If you connect a GPS unit, an accessory sold separately, position information based on GPS (Global Positioning
System) can be obtained.
