Modes Free-run, triggered, triggered with delay, doublet,
and gated. Triggered with delay, doublet, and
gated modes require an external trigger source.

Pulse width (Tw) 10 ns to 42 s
Delay (Td)
Free-run mode

Triggered with delay and doublet modes 75 ns to 42 s with ±10 ns jitter
Resolution
10 ns (width, delay, and PRI)
All modulation types (FM, AM, ΦM, pulse. and I/Q) may be simultaneously enabled except:
FM with ΦM, linear AM with exponential AM, and wideband AM with I/Q. AM, FM, and
ΦM can sum simultaneous inputs from any two sources (Ext1, Ext2, internal1, or internal2).
Any given source (Ext1, Ext2, internal1, or internal2) may be routed to only one activated
modulation type.
