Filters
Description Filters can be switch in and out freely except in
standard waveform shape where the filters are
automatically used by the instrument to reconstruct
the sine shape.
Type 25 MHz, Bessel; 50 MHz Bessel; 60 MHz Elliptic; 120
MHz Elliptic
General Run Modes
Description Define how waveforms start and stop. Run modes
description applies to all waveform types and
functions, except where noted otherwise.
Continuous Continuously free-run output of a waveform.
Waveform generation can be enabled and disabled
from a remote interface only.
Triggered Upon trigger, outputs one waveform cycle. Last
cycle always completed
Burst Upon trigger, outputs a single or multiple pre-
programmed number of waveform cycles. (Does
not apply to Sequence Mode). Burst is
programmable from 1 through 1M cycles
Gated Transition enables or disables generator output.
Last cycle always completed
Mixed Same as triggered except first output cycle is
initiated by a software trigger. Consequent output
requires external triggers through the rear panel
TRIG IN connector
