Turning the Interlocking of the Light Source and Optical Power
Meter Settings On and Off
You can connect an optical fiber between the light source port of an Instrument and the optical power
measurement port of another Instrument and use this setting so that the power meter settings are
synchronized to the light source wavelength and modulation mode settings.
On
After On is selected, the power meter settings are synchronized to the light source settings.
Off
The power meter settings are not synchronized to the light source settings.
Turning the Display of the Max/Min Value Menu On and Off
A menu can be displayed in the soft key menu for displaying the maximum and minimum measured
values.
ON
The menu is displayed.
OFF
The menu is not displayed.
Turning the Maximum and Minimum Value Display On and Off
On the menu displayed in the parameter screen, you can start the maximum and minimum
measurement display. During measurement, the displayed maximum and minimum values are
constantly updated.
ON
The displayed maximum and minimum values are updated starting from when the setting is turned on.
OFF
The maximum and minimum values are not updated. When set to off, the maximum and minimum
values are reset.
Offset
You can add a specified value (the offset value) to measured input optical power values and display
the results as measured values.
The range is –9.900 dB to 9.900 dB.
Threshold
You can set upper and lower threshold values and determine whether or not the measured values fall
within them.
• The range for upper and lower threshold values is –80 dBm to 40 dBm. The upper limit must be
greater than the lower limit.
• If the measured values are less than or equal to the upper limit and greater than or equal to the
lower limit, the corresponding bar graph is displayed in green.
• If the measured values exceeds the upper limit or fall below the lower limit, the corresponding bar
graph is displayed in red.
Holding the Measured Value Display
When you tap the HOLD soft key, the measured values, bar graph, maximum value, minimum value,
and the on/off state of the maximum and minimum value display are no longer updated. The values at
the time that you tapped the HOLD soft key remains displayed. To release the hold, tap the HOLD soft
key again.
Zero Set
Perform a zero-set whenever necessary, such as after you have turned on the power or when the
ambient temperature changes.
Performing zero set adjusts the internal deviation of the optical power measurement section and
enables you to obtain more accurate absolute optical power values. Perform zero set on the optical
power meter.
