Signal Output
DC Output of Jitter «See 7.1 for the operating procedure»
The jitter ratio of the selected measurement function can be converted to DC voltage (0
V to 5 V) and output from the jitter DC output connector on the rear panel. You can also
change the jitter ratio that corresponds to 0 V and 5 V.
Jitter ratio determination
You can specify the determination level in terms of a jitter ratio and output 5 VDC
when the data signal is less than or equal to the determination level and 0 VDC when
it is greater than the determination level.
DC output filter
This function takes a moving average of the measured jitter. When the DC output
fluctuates due to instability in the measured jitter, this function suppresses the degree
of fluctuation. You can set the number of measured values (average coefficient) to be
averaged in the range from 1 to 10.
When the average coefficient is set to 5

Monitor Output of RF Signal/Monitor Output of Equalized RF Signal «See 7.2 for the
operating procedure»
You can output the RF signal that is applied to the RF input connector directly to the
monitor output on the rear panel. If the equalizer is activated, the equalized RF signal is
output.
Data Signal Output «See 7.2 for operating procedure»
You can output the data signal obtained by slicing and binarizing the RF signal from the
data signal output connector on the rear panel at TTL levels.
Clock Signal Output «See 7.2 for operating procedure»
You can output the clock signal that is applied to the clock input connector or the clock
signal that is regenerated by the PLL circuit from the clock signal output connector on the
rear panel at TTL levels.
