To set how to measure bit error:
Set Gating Cycle at Gating.

Performs measurement until the time set at the
measurement period is exceeded.
Repeat: Performs measurement until ER Result button display
becomes Stop.
The bit error rate returns to 0 at each measurement
period.
Untimed: Performs measurement until ER Result button display
becomes Stop. The bit errors are accumulated.
The following figure shows the relationship between the Gating Cycle
setting and the change in the displayed bit error count.
