Signal Generators
Pulse Mode delivers a single pulse per trigger event to the
outputs. The pulse is programmable in delay and duration.
Burst Mode results in a “burst” of n pulses per trigger event,
with pulses configured similarly to single pulses in Pulse
mode.
Pattern Mode delivers a programmable pattern per trigger
event to the outputs. The pattern is programmable or may
be selected from a library of pre-configured patterns. The
pattern may be presented in either NRZ or RZ formats. In
NRZ mode, the pattern crossing point is programmable. In
RZ mode, the duration (duty cycle) of the pattern pulse is
programmable.
external Width Mode makes the pulse level follow the edges
of the Ext In input. A rising edge causes the output to go
high, while a falling edge causes the output to go low.
