Delay and off time
The delay is the time that the output remains at the bias level before the start of the pulse. Delay on
the Model 2461 can be from 0 s to 10,000 s; the default is 1 ms.
The off time is the time that the output remains at the bias level after the end of the pulse. Off time
can be 0 s to 10,000 s.
Figure 119: Pulse delay and off time
You do not need to have both a delay time and an off time for the pulse. For example, you can set the
delay to 0 s and the off time to any value you want (up to 10,000 s).
Pulse period
The pulse period is the time interval from the beginning of a pulse to the beginning of the next
consecutive pulse. This includes any delay time or off time that occurs between the pulses.
