Measured pulse modulation envelope
Internal pulse generator
Modes Free-run, triggered, triggered with delay, doublet,
and gated. Triggered with delay, doublet, and
gated require external trigger source.
Period (PRI) (T
p
) 70 ns to 42 s
(Repetition frequency: 0.024 Hz to 14.28 MHz)
Pulse width (T
w
) 10 ns to 42 s
Delay (T

)
Free-run mode 0 to ±42 s
Triggered with delay and doublet modes 75 ns to 42s with ±10 ns jitter
Resolution 10 ns (width, delay, and PRI)

Remote programming
Interfaces GPIB (IEEE-488.2,1987) with listen and talk, RS-232,
and 10-base T-LAN interface.
Control languages SCPI version 1992.0. Also will emulate most
applicable Agilent 836xxB, Agilent 8373xB, and
Agilent 8340/41B commands, providing general
compatibility with ATE systems which include these
signal generators.
IEEE-488 functions SH1, AH1, T6, TE0, L4, LE0, SR1, RL1, PP0, DC1,
DT0, C0, E2.
VXIplug&play drivers Are available.
