Procedure
Selecting the DC output mode
1. Press the SHIFT+<(UTILITY) key. The display shows the characters [init].
2. Turn the rotary knob to select [dcout].
3. Press the > key. Turn the rotary knob to select [Jitt] or [JudGE]. If you select
[Jitt] (jitter ratio output), a DC voltage corresponding to the jitter ratio is output
from the jitter DC output connector. If you select [JudGE] (determination
output), a DC voltage of 5 V is output when the jitter ratio is below the
determination level and 0 V when the jitter is above the determination level from
the jitter DC output connector.
Setting the jitter ratio output range
• Setting the upper limit of the jitter ratio output range
4. Press the SHIFT+<(UTILITY) key. The display shows the characters [init].
5. Turn the rotary knob to select [dc hi].
6. Press the > key. The display shows the upper limit of the jitter ratio output
range.
7. Use the rotary knob and arrow keys (< or >) to set the upper limit.
For the procedure to set numeric values, see section 3.7.
• Setting the lower limit of the jitter ratio output range
8. Press the SHIFT+<(UTILITY) key. The display shows the characters [init].
9. Turn the rotary knob to select [dc Lo].
10. Press the > key. The display shows the lower limit of the jitter ratio output
range.
11. Use the rotary knob and arrow keys (< or >) to set the lower limit.
For the procedure to set numeric values, see section 3.7.
