Increment Mode
Using the Increment System Mode
*Note: Dual Trigger Mode and Incrementing mode are mutually exclusive.
Also to get the first incremented pulse the :PULSe0:IRESet 1 command must be sent,
otherwise the pulse will not get incremented.
The System Increment modes are a pair of special modes, which allow the delay and width of each
channel to be incremented at the end of a burst of pulses.
Each channel is independent and each
may be set with different initial values and different values for the step size for both the delay and the
pulse width.
There are two incrementing modes, Burst Increment and Duty Cycle Increment. In the Burst
Increment mode, each start command or external trigger produces a burst of pulses. At the end of
the burst the appropriate delays and pulse widths are incremented and the instrument is armed for
the next start command. In the DC Increment (Duty Cycle) mode the output is started as with the
normal duty cycle mode. At the end of each cycle the delays and pulse widths are incremented.
This continues for the number of cycles defined by the Cycle parameters. The modes are selected
from the system mode menu. The step sizes are specified in the advanced channel menus.
