The MSO/DPO4000B Series Mixed-Signal Oscilloscope provides up to 20 channels of analog and digital signals in a single instrument to quickly detect and diagnose complex design problems. With a bandwidth of up to 1 GHz and up to 1x oversampling across all channels, you can observe fast-changing signals in detail. With a standard record length of up to 5 Mpoints (all channels), it can capture signals over long periods of time with high timing resolution. The MSO/DPO20B Series includes a rich set of features, including quick waveform control with the innovative Wave Inspector feature, automatic serial and parallel bus analysis, limit testing, and automatic power analysis, making debugging complex circuit designs easy and fast.
