Tektronix DPO3034 Digital Phosphor Oscilloscope

The Tektronix DPO3034 is a 4-channel Digital Phosphor Oscilloscope delivering 300 MHz analog bandwidth and 2.5 GS/s sample rate across all channels for high-fidelity signal capture and analysis. With 5 Mpoints record length per channel and >50,000 waveforms per second capture rate, it enables extended signal observation while maintaining 1.17 ns typical rise time. The instrument provides over 125 trigger combinations including runt and logic triggers, isolating specific events such as glitches, setup/hold violations, and bus data anomalies. Its 9-inch color LCD display with 800 × 480 resolution supports multiple viewing modes—vectors, dots, variable persistence, and infinite persistence—with intensity-graded waveform rendering.
