The HP/Agilent 54642A is a 2-channel, 500 MHz digital oscilloscope engineered for detailed signal acquisition and analysis in high-speed applications. With 8 MB of MegaZoom deep memory, a 2 GSa/s sample rate, and advanced triggering capabilities spanning edge, pulse width, video, pattern, and serial protocols (I²C, SPI, LIN, CAN, USB), this instrument delivers both capture depth and precision event isolation. The 6.3-inch color TFT display with 25 million vector/sec refresh rate renders waveforms with superior clarity, while integrated math functions—FFT, arithmetic operations, and calculus—enable in-depth signal characterization without external analysis tools.
