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.
