The Tektronix DPO7254 is a 2.5 GHz Digital Phosphor Oscilloscope engineered for signal acquisition and analysis in complex electronic designs. It delivers real-time waveform capture rates exceeding 250,000 waveforms per second, combined with up to 40 GS/s sample rate on a single channel and optional record lengths up to 500 M points. Advanced triggering—including over 1400 Pinpoint® combinations and serial pattern triggering up to 1.25 Gb/s—isolates transient events and protocol-specific anomalies. The four-channel vertical system achieves 145 ps rise time and includes DSP bandwidth enhancement to 3.5 GHz, enabling analysis of high-speed signals with 25% greater vertical measurement resolution across 10 vertical divisions.
