The Agilent/Keysight 54645A is a 100 MHz, dual-channel digital oscilloscope engineered for signal acquisition and analysis across applications ranging from general circuit troubleshooting to detailed transient characterization. The instrument combines 1 MB memory per channel with MegaZoom technology, delivering responsive waveform navigation and deep memory capture capabilities. Maximum sample rates reach 10 GSa/s in repetitive mode, with 200 MSa/s single-shot performance and 20 MSa/s continuous acquisition. The display updates at up to 3 million points per second, enabling real-time visualization of complex signals.
