s can record lengths up to 125 bytes with realtime sampling rates to 200 Ms/sec (mega samples per second) and feature Fast-Fourier transforms (FFT) for signal analysis. The DSO's also have a zoom function for expanding a segment of waveforms of interest, 20 automatic waveform measurements, and USB interface for high-speed communication with a PC. They can serve as autoranging, 6,000-count true-RMS DMM's with 600-V Category III ratings and 600-A current.
