(6) Number of analysis points display
(7) Green frame is the active zone. To activate the gray frame, touch the gray frame to switch to green.
(7)-1 When the trace starts, the red lamp for each CH is lit.
(7)-2 The set CH and range are displayed.
(7)-3 When the set range is other than Off, the green lamp is lit. When the value is scaled over, the red
lamp is lit.

Set this setting for only the channel you have set the Linear, Power, PSD, Cross, TRF, and Coherence.
None, Differential, D-Differential, Integral, or D-Integral can be set as the possible calculation.
"Set this setting only when Linear, Power, PSD, or Cross is set.
When this setting is On, Y Axis is displayed with RMS scale.
"When the moving average is performed with any frequency width with respect to the results
of FFT calculation, the waveform is smoothed.
You can select from the items that are calculated from the analysis frequency and the number
of analysis points.
