The Oscilloscope At a Glance
Choose from a variety of oscilloscopes
all with 2 GSa/s sample rate and 
2 MBytes of MegaZoom deep memory 
per channel for capturing long, 
non-repeating signals.
• Agilent 54641A - 2-channel, 350-MHz 
bandwidth
• Agilent 54641D - 2-channel +16 logic 
channels, 350-MHz bandwidth
• Agilent 54642A - 2-channel, 500-MHz 
bandwidth
• Agilent 54642D - 2-channel +16 logic 
channels, 500-MHz bandwidth
Display shows current input signals 
• All analog and digital (54641D/42D) 
channels displayed in main and 
delayed mode
• Indicators for channel, time base, 
digital (54641D/42D) channel activity, 
trigger and acquisition status 
• Softkey labels 
• Measurement results 
Digital channel controls select, 
position, and label inputs (54641D/42D)
• Turn channels on or off individually or 
in groups of 8 
• Rearrange order of channels to group 
related signals  
• Create and display labels to identify 
channels 
General controls measure, save and 
restore results, and configure the 
oscilloscope 
• Waveform math including FFT, 
subtract, multiply, integrate, and 
differentiate 
• Use Quick Meas to make automatic 
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 1 ns/div to 
50 s/div 
• 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) 
Run control keys begin and end data 
acquisition 
• Run/Stop starts and stops continuous 
acquisitions 
• Single performs one acquisition 
• Infinite persistence accumulates and 
displays the results of multiple 
acquisitions 
Trigger keys define what data the 
oscilloscope will trigger on 
• Source key allows conventional 
oscilloscope triggering
• Modes include Edge, Pulse Width, 
Pattern, CAN, Duration, I
2
C, LIN, 
Sequence, SPI, TV, and USB 
triggering
Softkeys extend the functionality of 
command keys 
Select measurement types, operating 
modes, trigger specifications, label data, 
and more 
Digital channel inputs through a flexible 
probing system (54641D/42D)
• Sixteen channels through a dual 
8-channel cable with micro-clips 
• Set logic levels as TTL, CMOS, ECL, or 
to a user-definable voltage
Utilities 
• Dedicated parallel printer port, 
controller operation, floppy disk 
storage
Built in Quick Help system
• Press and hold any key front-panel 
key or softkey to get help in 11 
languages.
