Selecting the waveform to zoom
Select the waveform to zoom from the following choices.
CH1 to CH8, Math1, Math2
However, the waveforms that are turned OFF according to the settings described in
section 9.1, “Selecting the Channel to Display” cannot be zoomed.
Setting the zoom factor
• The maximum zoom factor that can be selected depends on the display record
length and observation time. For example, the maximum zoom factor is 10,000
times when the observation time is 20 s and the display record length is 100 k-
words. It is 100,000 times when the observation time is 20 s and the display record
length is 1 M-word or 4 M-words. The maximum zoom factor becomes smaller as
the display record length gets shorter.
• You can select different zoom factors for Z1 and Z2 (the two zoom sections).
• When there are less than 500 points of sampled data on the time axis because the
display record length is less than the number of displayed points or the waveform is
expanded too much, the display points are interpolated.
• To set the zoom factors of Z1 and Z2 simultaneously, Z1 and Z2 must both be
selected as described in the previous section, “Selecting the type of zoom display.”
