Settings related to jitter measurement items*
TJ Measurement
BER
Sets the BER to measure TJ(User Define) and Eye Opening with the
measurement result.
Selectable up to 1.0E–001 to 1.0E–018, in 1.0E+001 Step
Fixed RJ
Function to use User-specified value for RJ results
“ON”: Uses the value of Fixed RJ Factor
“OFF”: Uses the calculation result for jitter categorizing.
RJ Value
The value to be used when Fixed RJ is ON
0.01 to 999.99 ps, step 0.01 ps rms
Correction Factor
Function to correct results by Users
“ON”: Corrects the result.
“OFF”: Does not correct the result.
DJ (Scale)
Function to adjust Scale of DJ DJ = DJ (Scale) × Measurement result
0.01 to 999.99, step 0.01
RJ (Scale)
Function to adjust Scale of RJ RJ = RJ (Scale) × Measurement result
0.01 to 999.99, step 0.01
RJ (rms)
Function to adjust rms of RJ
( ) ( ){ }

rmsRJ-resultt MeasuremenRJ =
0.01 to 999.99 ps rms, step 0.01 ps rms
Define Threshold
Definition of Crossing value to measure jitter
Auto: Automatic adjustment with the use of Crossing value of Scope
Manual: User input of Crossing to be measured
Manual Crossing
Crossing value to measure jitter
30 to 70%, step 1%
PDJ Measurement
Function to switch Pattern Dependent Jitter measurement method.
Available at Advanced Jitter.
“ON”: Displays the result to regard DDJ as PDJ.
“OFF”: Displays the result to regard DDJ as DDJ.
PDJ Standard
Filter
When PDJ Measurement is ON, the following filters are used for PDJ
measurement depending on the Standard. Unit is Hz.

Measurement Edge
Type
Switching of Edge to measure jitter
Available at Advanced Jitter.
“ALL”: Measures both rising and falling transition.
“Rising”: Measures only rising transition.
“Falling”: Measures only falling transition.
Depending on this setting, the result on the graph also displays the
corresponding transition result.
*: Available when MP2110A-096 is installed.
