to the product or loss of important
data. Do not proceed beyond a
CAUTION notice until the indicated
conditions are fully understood and
met.
WARNING
A WARNING notice denotes a
hazard. It calls attention to an
operating procedure, practice, or
the like that, if not correctly per-
formed or adhered to, could result
in personal injury or death. Do not

Agilent 3000 Series Oscilloscopes—At a Glance
The Agilent 3000 Series oscilloscopes are low-cost portable
digital storage oscilloscopes (DSOs) that deliver these
powerful features:
• Two- channel models and bandwidths:
•DSO3062A: 60 MHz.
•DSO3102A: 100 MHz.
•DSO3152A: 150 MHz.
•DSO3202A: 200 MHz.
• Bright 5.7 inch QVGA (320 x 240) 64K TFT color LCD
display.
•Upto1GSa/ssamplerate.
• Up to 4 kpts memory.
• Automatic voltage and time measurements (20) and
cursor measurements.
• Advanced triggering (edge, pulse width, and video).
• Math function waveforms: add, subtract, multiply, FFT.
• USB ports (1 host with rear panel module, 1 device).
The USB host port is used for easy printing, saving, and
sharing of waveforms, setups, screen BMP files, and CSV
data files.
The USB device port is used with the Scope Connect
software only. This port cannot be used for programming
the oscilloscope.
• Internal storage for 10 waveforms and 10 setups.
• Special digital filter and waveform recorder.
• Built- in 5- digit hardware frequency counter.
• Multi- language (11) user interface menus.
