New mixed-signal testing power
With the introduction of the Agilent
Technologies 54645D mixed-signal
oscilloscope (MSO) to your lab, you
will be able to easily view the complex relationships of your circuit’s
analog and digital operation.
Seamless integration of scope and
logic channels in the 54645D MSO
allow you to view both the analog circuit operation on the two 100 MHz
scope channels and the logic timing
displayed on the 16 logic channels.
Analog and digital events are aligned
in time so that you can easily relate
cause and effect in many difficult
mixed-signal troubleshooting situations, such as those encountered in
debugging 8- or 16-bit microcontroller
The 54645D gives you an oscilloscopelike operation of both the scope and
logic channels. For example, simply
turn the time-base knob to set the
time/division for all scope and logic
channels. Press Autoscale for the display of all active analog (scope) and
digital (logic) channels. There is no
scope-logic mode switch, just a seamless integration of logic channels into
a scope.
Agilent MegaZoom Technology
When you try to view analog and
digital signals, the events of interest
either take place over a long time
span or they are widely separated
from the trigger event. With 1 million
samples per channel, MegaZoom technology captures long time spans
while maintaining the high sample
rate, allowing you to see the fine
detail needed to solve elusive
Before the introduction of the 54645D
MSO with MegaZoom technology,
deep-memory oscilloscopes were considered specialized tools because of
their complex operation, non-responsive control panel, and excessive dis-
play dead time. These problems have
been greatly reduced with the development of MegaZoom technology,
which uses multiple processors optimized for the task of waveform acquisition, storage, and display. Now you
can have a deep memory scope in
your lab that is also a scope you will
use every day, as it is a deep-memory
scope that responds instantly to your
control inputs, has a high speed, low
dead time display and deep memory
with easy-to-use pan-and-zoom.
With an easy-to-use control system,
the 54645D MSO provides the triggering power you need to troubleshoot
problems. You will find it ideally suited
for everyday use because of its familiar scope edge triggering mode. This
familiar scope mode is the one that
can be used to solve most of your
problems, as you can trigger on a rising or falling edge on any of the
MSO’s 18 input channels.
Pattern triggering is provided in the
54645D MSO. This triggering mode
allows you to establish a trigger pattern of high, low, and “don’t care”
levels across all 18 of its channels.
The advanced mode gives you the
choice of glitch, TV, and advanced
pattern triggering. In the glitch mode,
the 54645D MSO can search for a
glitch that is less than a specified
width on any of its 18 input channels,
allowing you to find abnormally short
pulses that may indicate circuit failures. In addition you can search for a
pulse that is greater than a specified
width or within upper and lower limits.
In advanced pattern trigger mode, the
54645D MSO will search for a combination of two trigger pattern terms.
These terms may be combined in one
of several Boolean relationships
In TV mode the 54645D MSO may be
triggered on field 1, field 2, or line of
a composite TV waveform.
Computer and hardcopy I/O
For connection to your PC, printer, or
workstation, the 54645D is fully compatible with the full line of 546XX
interface modules. Select the module
that best fits your needs and you are
ready to either print the screen or
interface to your PC or workstation.
With the addition of the 54657A or
54659B Measurement/Storage module
you will have both the interface capabilities described above, as well as
additional measurements such as
Software for enhanced connectivity
With the addition of HP BenchLink
Scope software for Microsoft®
Windows™, you have the ability to
easily interface this powerful instrument to your PC. This versatile software, which is compatible with
Windows 3.1, 95 or NT, makes the
movement of waveform data or trace
images fast and easy.
Built to last
The 54645D MSO is designed and
built to the rugged requirements of
MIL-T-28800. This means that the
product is built to withstand the rigors of daily use as you test and debug
your circuits, backed up with a threeyear warranty.
