Rat
e
Data Clock Rate Sets input data speed, clock frequency, and frequency
dividing rate.
Tracking*
1
Specifies Symbol Rate whether to follow the Bit Rate of
PPG/ED Ch1.
Off:
Symbol Rate does not follow PPG Bit Rate nor CRU
Rate.
Symbol Rate: PPG, Divide Ratio: Clock Output:
Symbol Rate follows PPG Bit Rate.
Divide Ratio follows PPG Clock Out.
Symbol Rate: PPG, Divide Ratio: Sync Output:
Symbol Rate follows PPG Bit Rate.
Divide Ratio follows PPG Sync Out.
Symbol Rate: PPG, Divide Ratio: User Defined:
Symbol Rate follows PPG Bit Rate.
Symbol Rate: CRU: 2*
2
:
Symbol Rate follows CRU Rate. Divide Ratio is
determined as follows, depending on which CRU to
track and its setting.
MP2110A-054: 2
MP2110A-055: 4 when the operation rate is 20G
band.
8 when the operation rate is 50G
band.
Tracking Target*
3
Sets which CRU to track the setting when Symbol Rate: CRU
is selected for Tracking.
26G:
26G CRU
53G: 53G CRU
Recalculate Option Clock Rate: Calculates Clock Rate from Symbol Rate and
Divide Rate.
Symbol Rate: Calculates Symbol Rate from Clock Rate and
Divide Rate.
Clock Rate Sets clock frequency input to
Trigger Clk In
connector.
Divide Ratio Sets frequency dividing rate (Symbol Rate/Clock Rate).
Symbol Rate When Tracking is Off, Sets signal symbol rate to be
measured.
Acquire Clock Rate Measures clock frequency input to
Trigger Clk In
connector.
Divide Ratio Detect Sets whether to detect frequency dividing ratio of clock signal
input to
Trigger Clk In
connector. The automatic detection of
the dividing ratio and the Divide Ratio resetting are
preformed when this item is set to On or Auto Scale is
executed.
Precision Trigger*
4
On, Off Enables or disables the precision trigger.
Reset Resynchronizes the trigger when the precision trigger is set
to On.
*1: An error message is displayed because the Tracking operation is not
performed when one or both of the following conditions is/are met.
