Keysight 1000B Series Oscilloscopes—At a Glance
The Keysight 1000B Series oscilloscopes are low-cost portable digital storage
oscilloscopes (DSOs) that deliver these powerful features:
• Channel counts, input bandwidths, sample rates, and memory depths shown
in the following table:
• Bright 5.7 inch QVGA (320 x 240) TFT color LED display and small footprint (to
save bench space).
• Up to 400 wfms/s refresh rate.
• Automatic voltage and time measurements (22) and cursor measurements.
• Powerful triggering (edge, pulse width, video, and alternate modes) with
adjustable sensitivity (to filter noise and avoid false triggers).
• Math function waveforms: add, subtract, multiply, FFT.
• USB ports (host and device) for easy printing, saving, and sharing of
waveforms, setups, screen BMP files, and CSV data files.
• Internal storage for 10 waveforms and 10 setups.
• Special digital filter and waveform recorder.
• Built-in 6-digit hardware frequency counter.
• Multi-language (11) user interface menus and built-in help.
