Measured pulse modulation envelope

Frequency = 9 GHz, amplitude = 10 dBm, ALC off, 10 ns/div

Internal pulse generator (Option UNU or UNW)

Modes Free-run, triggered, triggered with delay, doublet, and gated. Triggered with delay, doublet, and

gated require external trigger source.

Period (PRI) (Tp) 70 ns to 42 s (repetition frequency: 0.024 Hz to 14.28 MHz)

Pulse width (Tw) 10 ns to 42 s

Delay (Td)

Free-run mode 0 to ±42 s

Triggered with delay and doublet modes 75 ns to 42 s with ±10 ns jitter

Resolution 10 ns (width, delay, and PRI)

Simultaneous modulation

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.
