CAUTION
Do not apply external voltage to the output connector. This may cause damage

Setting the jitter ratio output range
You can set the upper and lower limits of the jitter ratio output range. The upper and
lower limits correspond to 5 VDC and 0 VDC, respectively.
• Range: 0.00% to 100.00%
• Resolution: 0.01%
Setting the determination level
You can set the determination level for the determination output.
• Range: 0.00% to 100.00%
• Resolution: 0.01%
Setting the average coefficient of the DC output filter
Takes the moving average of the jitter that has been measured. When the DC output
fluctuates due to instability in the measured jitter, this function suppresses the degree
of fluctuation. You can set the average coefficient (number of measured values to be
averaged) when performing moving average. The jitter ratio that is moving-averaged
using the DC output filter is applied to both the jitter ratio output and the determination
output. The measured value that is moving averaged is used for the numeric display,
meter indication, and DC output.
