The front-panel controls of the 9450A
have been laid out in the style of an
analog oscilloscope, making it easy to
use from the very first moment. The
analog feel is enhanced by the rapid
instrument response and the fact that
waveforms are presented instantly on
a
bright high-resolution screen. For
automated test applications at1 the
front-panel controls, including cursor
positions and internal functions, are fully
programmable over RS-232-C or
interfaces.
Capturing and measuring signals has
never been easier. For repetitive signals
an auto-setup facility finds and displays
signals in less than

LONG NOH-VOLATILE MEMORIES
Only long memories allow high-fidelity
recording over extended periods of time.
On equal time-base settings the 9450A,
with 50K of memory per channel, will
sample waveforms up to 50 times faster
than an oscilloscope with only
memory. Faster sampling means better
single-shot bandwidth, better time
resolution and the power to expand
waveforms up to 1000 times to see
details that completely elude other
digital oscilloscopes. In addition, when
segmented, the
acquisition memories can store up to
200 waveforrns/channel (complete with
date and time stamps).

TRIGGER
Push-button control enables the user to
choose the appropriate trigger functions
for his signal: standard triggering for
basic measurements and advanced
triggering to meet highly sophisticated
requirements.
The standard trigger facility provides all
the conventional trigger functions. Front-
panel controls select and adjust param-
eters such as pre- and post-trigger
settings, trigger level, slope, mode and
coupling. To help users quickly deter-
mine the
conditions,
of illustrative trigger graphics.
SMART triggering offers a solution to
even the most intricate triggering
problems. For example, FASTGLITCH
trigger can be used to locate and reveal
glitches and spikes less than 2.5 nsec
wide. Time-qualified trigger
ranging applications and can be used to
ignore unwanted signal
trigger features include hold-off (by time
or number of events), gated triggering
and conditional triggering, qualified
trigger, and trigger delayed
number of events.
The PASSiFAlL routine enables the
oscilloscope to compare a source
against a tolerance mask while simultaneously testing
parameters.
