One-Action Keys
This is the general name for a key that uses data from the active trace waveform (the
currently displayed waveform) to set measurement conditions.
Setting conditions requires that a waveform is displayed for the active trace.
PEAK →CENTER
Sets the wavelength (frequency / wavenumber) of the peak value to the center
wavelength (frequency / wavenumber).
After execution, the center wavelength (frequency / wavenumber) set in the center
wavelength (frequency / wavenumber) setting screen is displayed. The center frequency
(frequency / wavenumber) can be changed after the setting is made initially.
MEAN WL→CENTER
Sets the RMS center wavelength of the spectrum lowered by the threshold value (20
dB) from the waveform peak of the active trace to the center wavelength (frequency /
wavenumber). The center wavelength (frequency / wavenumber) can be changed after
the setting is made initially.
VIEW→MEAS
This key is used to set the currently set ZOOM scale (ZOOM CENTER, ZOOM SPAN,
ZOOM START, ZOOM STOP) as the measurement scale (CENTER, START, STOP,
SPAN).
When you press this key, the current waveform display scale is set as the measurement
scale for the next sweep.
