The Tektronix DPO4034B is a 350 MHz, 4-channel digital phosphor oscilloscope built for rapid isolation and analysis of complex signals in modern electronic designs. Its waveform capture rate exceeds 50,000 waveforms per second, dramatically increasing the probability of catching infrequent anomalies like runt pulses and glitches. The instrument combines advanced triggering—including edge, pulse width, runt, logic, setup and hold, and serial bus triggers for I2C, SPI, USB, Ethernet, CAN, LIN, FlexRay, and UART protocols—with 41 automated measurements, FFT analysis, and waveform histograms to accelerate debug cycles and design verification.
