The Tektronix TDS3012B is a 100 MHz digital phosphor oscilloscope engineered for signal analysis and troubleshooting in laboratory and field environments. Built on Digital Phosphor Oscilloscope (DPO) technology, it captures real-time, three-dimensional representations of signal behavior across amplitude, time, and amplitude distribution. This capability reveals transient events and waveform anomalies that conventional digital storage oscilloscopes often miss. The instrument combines fast waveform capture at 3,600 waveforms/second with peak detection down to 1 ns glitches, making it effective for identifying infrequent signal events and characterizing complex signal interactions.
