Mode Menu

F1: CONT - (Continuous) - Selects continuous output.

F2: TRIG - (Triggered) - Triggers one output cycle of the selected pulse for each trigger event.

F3: GATE - (Gated) - Triggers output cycles as long as the trigger source asserts the gate signal.

F4: BRST - (Burst) - Triggers output N output cycles for each trigger event, where N ranges from 2 to

999,999.

F5: EXTWID - In the external width (EXT WID) pulse mode, the pulse period and width are determined

by the externally applied signal. The SEFRAM 4451 then applies transition and level

parameters to this signal in order to generate the pulse. The period, width and delay may be

changed, but their change has no effect on the pulse, and their values are not displayed. The

trigger mode may not be changed while the external width pulse mode is enabled.
