HP / Agilent 54502A 400 MHZ DIGITIZING OSCILLOSCOPE

The HP/Agilent 54502A is a 400 MHz digitizing oscilloscope designed for signal acquisition and analysis in design verification, manufacturing test, and research environments. This dual-channel instrument captures both repetitive and single-shot signals with real-time sampling up to 400 MSa/s and delivers 400 MHz bandwidth in repetitive mode, 100 MHz in single-shot mode. With 2001-point memory depth in real-time acquisition and programmable triggering down to 1.75 ns glitch detection, the 54502A provides the timing resolution and measurement capability required for precision electronic testing.
