Displaying Determination Results
The determination result is displayed in the JUDGE area on the front panel.
When the jitter ratio is less than or equal to the determination level set in step 2,
the green GO indicator illuminates. When the jitter ratio exceeds the
determination level set in step 2, the red NO-GO indicator illuminates. If a clock
signal can not be regenerated by the PLL circuit during D-to-C measurement,
both GO and NO-GO indicators illuminate in green and red respectively.
You can set the determination level for the jitter ratio and display determination results in
the JUDGE area of the front panel. The GO indicator illuminates in green when the jitter
ratio is below the determination level, and the NO-GO indicator illuminates in red when
the jitter ratio exceeds the determination level. The determination level specified here
also applies to the determination level of the jitter ratio determination output (section 7.1).
You can set the determination level in the range shown below.
Setting range: 0.00 to 25.00% (in steps of 0.01%)
