Publication No. 980935 Rev. A
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. Trigger can be internal or
external.
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. Bust triggering can be
internal or external.
Gated
Transition or level enables or disables generator
output. Last cycle always completed
