The Tektronix DPO7254C is a 4-channel, 2.5 GHz digital phosphor oscilloscope engineered for deep analysis of complex mixed-signal designs. It captures signal anomalies, transients, and rare events with exceptional waveform acquisition rates exceeding 250,000 waveforms per second, enabling rapid identification of intermittent faults and design issues.
This instrument combines high sampling capability—up to 40 GS/s on a single channel—with flexible record lengths reaching 500 Mpts (optional) to preserve signal detail across extended time windows. The 12.1-inch XGA color touchscreen with intensity-graded and color-graded digital phosphor display renders waveforms with exceptional clarity, while the 8-bit vertical resolution (expandable to 11-bit via high-resolution mode) ensures accurate amplitude measurement.
