The Tektronix DPO2002B is a 70 MHz, 2-channel digital phosphor oscilloscope built for real-time signal characterization and anomaly detection. It captures waveforms at up to 5,000 wfm/s, making infrequent events—glitches, runt pulses, and transient faults—visually apparent through real-time intensity grading. The instrument samples at 1 GS/s across all channels with 1 Mpoint record length and 5 ns rise time, enabling detailed capture over timescales from 4 ns to 100 s.
