trigger initiated
|
May be pushbutton or external
trigger initiated
|
|
amplitude
|
Each channel may provide
a burst from 1 to 1,000,000 pulses at the internal rep rate.
The Burst mode is selectable for each channel and each of
those channels may have an independent number of pulses.
|
|
Duty Cycle
|
This mode allows the timing
events to be ON for M pulses and then OFF for N pulses. Divide
by n can be achieved by setting M to 1 and N to (n-1).
