Configuration of the instrument
Time Interval between Scans
This parameter allows to enter a wait period before the measurement start (only active
if Long Term is positioned on Yes, in Continue or Statistics mode)
•
Increments of 5 seconds up to 1 minute, then increments of 1 minute up to 10
minutes, then increments of 5 minutes up to 60 minutes; then increment of 1 hour
up to 24 hours.
The modification of this parameter automatically modifies the next parameter, Total
Meas. Time, which cannot be modified.
Analysis parameters
In the Setup page, press Analysis softkey (if one parameter is selected in the current
screen, press Top Menu soft key to display the right menu keys and click on Analysis).

Min. Channel spacing
Defines the minimum spacing of two adjacent optical channels in the system.
This parameter is also used to set the range for integration to measure the accurate total
signal power of an optical channel. (see table contents
channel power integration will be ±1/2 the min. channel spacing setting left and right to
the channel center frequency.
The measurement result will be displayed in the WDM table as 'Level' in dBm.
1.Attention: all modification of these parameters has immediate repercussions on
the trace and entails the loss of the measurement statistics.
