It samples at 2.5 GSa\/s with 100 Mpts memory depth standard, and Ultra Phosphor 3.0 acquisition pushes the waveform capture rate to 1,000,000 wfms\/s in sequence mode — sixteen times the vertical detail of an 8-bit scope, held at full bandwidth without ERES averaging or sample-rate trade-offs. The 10.1-inch capacitive multi-touch display, on-instrument 4 Mpts FFT, 9 standard protocol decoders, and built-in WebServer round out a six-instrument bench in a single chassis.\u003c\/p\u003e\n\u003cp\u003eThe four-channel UPO2204HD is the flagship of the UPO2000HD family — 200 MHz bandwidth, four simultaneous analog channels, 70 µVrms background noise, and 12-bit resolution at the full bandwidth without ERES or sample-rate compromise.
