1
Period-Jitter 1σ
This parameter represents standard deviation (
1σ) on cycle distribution data at the time when the output clock cycles are
sampled 1000 times consecutively with the TDS7104 Digital Phosphor Oscilloscope of Tektronix Japan, Ltd.
2
Period-Jitter MIN-MAX
This parameter represents a maximum distribution width on cycle distribution data at the time when the output clock cycles are
sampled 1000 times consecutively with the TDS7104 Digital Phosphor Oscilloscope of Tektronix Japan, Ltd.
3
Output Lock Time
This parameter represents elapsed time after power supply turns ON to reach a voltage of 3.0 V, after the system is switched from
Power-Down state to normal operation state, or after the output frequency is switched, until it is stabilized at a specified frequency,
respectively.
