One-Action Keys <<See section 5.4 to 5.6 for the operating procedure>>
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.
One-Action Key Name
Description
PEAK → REF LEVEL
Sets the peak level of the measured waveform of the active trace
as the reference level.
MARKER→ REF LEVEL
Sets the moving marker level as the reference level.
PEAK→CENTER
Sets the peak wavelength or the peak frequency of the active
trace measurement waveform to center wavelength or center
frequency.
MEAN WL→CENTER
Sets THRESH 3 dB center wavelength or center frequency of the
active trace measured waveform to center wavelength or center
frequency.
VIEW→MEAS
Sets the currently displayed ZOOM scale as the measurement
scale (CENTER, START, STOP, SPAN) for the next sweep.
MARKER →CENTER
Sets the wavelength of the moving marker to center wavelength or
center frequency.
Δλ→SPAN
Sets the sweep width as six times the RMS 20 dB width of the
active trace measurement waveform.
MKR L1-L2 →SPAN
Sets spacing between line markers 1 and 2 for sweep width.
PEAK→ZOOM CTR
Sets the peak wavelength of the active trace measurement
waveform to center wavelength or center frequency of zoom
display.
MARKER →ZOOM CTR
Sets the wavelength of the moving marker to center wavelength or
center frequency of zoom display.
MKR L1-L2 →ZOOM SPAN Sets spacing between line markers 1 and 2 for sweep width of
zoom display.
Switching between Vacuum Wavelength and Air Wavelength
<<See section 5.2 for the operating procedure>>
This function switches the measured wavelength to either a vacuum wavelength or an air
wavelength.
Measurement can be performed in either air or vacuum wavelength mode.
Switching between Wavelength and Frequency
<<See section 5.2 for the operating procedure>>
This function switches the horizontal axis display to wavelength or frequency.
You can display either the wavelengths or frequencies of marker values and analysis
results.
Averaging <<See section 5.10 for the operating procedure>>
This function performs multiple measurements and displays the average values.
The function is used in cases such as: when the light source’s level is fluctuating; when
measuring a modulated signal of several kHz or less; when the waveform is disrupted
and difficult to measure; when it is necessary to obtain even higher measurement
sensitivity.
