The Tektronix DPO4104B Digital Phosphor Oscilloscope can analyze up to 4 analog signals with a single instrument to quickly find and diagnose problems in complex designs. Bandwidths up to 1 GHz and a minimum of 5x oversampling on all channels ensure you have the performance you need to see fast-changing signal details. To capture long windows of signal activity while maintaining fine timing resolution, the DPO4104B offers a deep record length of 20M points standard on all channels. With Wave Inspector® controls for rapid waveform navigation, automated serial and parallel bus analysis, limit and mask testing, and automated power analysis
