The DS1150 utilizes a 16-bit high speed microprocessor that enables the oscilloscope to typically acquire at a rate of 100,000 points per second to speed updates to the display.

The 32 kB of memory allows captured waveforms to be zoomed in and analyzed in detail.  Also, the built-in 10 ns peak detection circuit enables capture of high frequency noise, even at a low speed time/div settings.  The noise can be then magnified and analyzed with the zoom-in function.  10 waveforms and front panel set ups can be saved.  Previously exclusive to high-priced oscilloscopes, the built-in FFT provides diversified analysis.
