The HP 54645A/D at a Glance
Display shows current input signals
•
Eighteen (18) channels in main mode;
2 scope and 8 timing channels in
delayed mode (HP 54645D)
•
Indicators for peak, avg, or normal
acquisition, time base, channel
activity, trigger and acquisition status
•
Softkey labels
•
Measurement results
Channel Controls select, position, and
label inputs
•
Turn channels on or off individually
or in groups of 8 (HP 54645D)
•
Rearrange order of channels to
group related signals (HP 54645D)
•
Create and display labels to identify
channels (HP 54645D)
General Controls measure, save and
restore results, and configure the
oscilloscope
•
Make automatic time and frequency
measurements
•
Use cursors to make manual
measurements
•
Save or recall measurement
configurations or previous results
•
Autoscale performs simple
one-button setup of the oscilloscope
Horizontal Controls select sweep speed
and delay parameters
•
Sweep speeds from 5 ns to 50 s/div
(2 ns to 50s/div for HP 54645A)
•
Delay control moves waveform
display to point of interest
•
Delayed mode and delay allow
zooming in to show a portion of
waveform in detail (split screen)
Storage Keys begin and end data
acquisition
•
Run/Stop starts and stops continuous
acquisitions
•
Single performs one acquisition
•
Autostore accumulates and displays
the results of multiple acquisitions
•
Erase clears the current acquisition
and all accumulated data
Trigger Keys define what data the
oscilloscope will trigger on
•
Source key (HP 54645A) allows
conventional oscilloscope triggering
•
Edge mode allows triggering on a
positive or negative edge of any
single channel (HP 54645A/D)
•
Pattern mode allows triggering on a
pattern of channels either high, low,
or don’t care, with an optional single
edge qualifier (HP 54645D)
•
Advanced mode allows sequential
triggers, combined patterns, patterns
and edges, pattern durations, glitch
(HP 54645A/D), and TV (HP 54645D)
Softkeys extend the functionality of
command keys
Select measurement types, operating
modes, trigger specifications, label data,
and more
Channel Inputs through a flexible
probing system
•
Sixteen channels through a dual
8-channel cable with micro-grabbers
(HP 54645D)
•
Set logic levels as TTL, CMOS, ECL,
or to a user-definable voltage
(HP 54645D)
