Waveform Display and Information Display
Explanation
Zooming on the Waveform
Zoomed waveforms of two locations can be displayed simultaneously (dual zoom). You
can also specify which channels to zoom. Zooming is not possible if the number of
displayed points on the screen is less than or equal to 10 (less than or equal to 50 for
FFT waveforms).
Display Mode of Zoomed Waveforms
Main: Displays only the main (unzoomed) waveform.
Z1 Only: Displays only the zoomed waveform of zoom box Z1.
Z2 Only: Displays only the zoomed waveform of zoom box Z2.
Main&Z1: Displays the main waveform in the top window and zoomed waveform of
zoom box Z1 in the bottom window.
Main&Z2: Displays the main waveform in the top window and zoomed waveform of
zoom box Z2 in the bottom window.
Z1&Z2: Displays the zoomed waveform of zoom box Z1 in the top window and the
zoomed waveform of zoom box Z2 in the bottom window.
Main&Z1&Z2: Displays the main waveform in the top window, the zoomed waveform of
zoom box Z1 in the lower left window and the zoomed waveform of zoom
box Z2 in the lower right window.
Zoomed Trace (Allocation)
The traces whose Allocation is turned ON are zoomed. If the allocation is OFF, the trace
is not zoomed. You cannot allocate channels whose display is turned OFF.
Display Format of Zoomed Waveforms
As with the normal waveform, six display formats (Main*, 1 Zone, 2 Zone, 3 Zone, 4
Zone, 8 Zone, and 16 Zone) are available. You cannot set different formats for Z1 and
Z2.
* Selecting Main results in the same format as Main Format in the DISPLAY menu.
Zoom Rate (Z1 Mag/Z2 Mag)
• Sets the record time that is displayed in the zoom box.
• If the time base is set to an external clock signal, select the magnification from the
following:
×2, ×2.5, ×5, ×10, ×25, ×50, ×100, ×250, ×500, ×1000, ×2500..., ten-fold multiples of1,
2.5, 5, up to ×1000000
• The maximum zoom rate varies depending on the display record length.
Maximum zoom rate: Display record length ÷ 10
• The maximum magnification during realtime recording with respect to the record
length of the main waveform is as follows:
Main Waveform Record Length Record Length of the Zoom Window
1 M or 10 MW 250 kW
25 MW 500 kW
50 MW 1 MW
1000 MW or more 2.5 MW
• For details on the record length, see appendix 1.
• You can set different zoom rates for Z1 and Z2 (zoomed waveform of two locations).
