The HP 54601A oscilloscope provides the familiar, easy-to-use controls and interactive displays you've grown accustomed to on analog scopes. Yet, to solve your most difficult test problems, these scopes provide powerful digital features, such as pre-trigger viewing, waveform storage, and measurement automation. The 54601A features a real-time vector display that gives you a clear and accurate picture of your waveforms. The multi-processor architecture delivers a display update rate of over 500,000 points per second. In vector mode, it provides a fast screen refresh rate of 60 times/second, regardless of the number of waveforms displayed, and minimal display blind time so you can capture and display infrequent events that other scopes might miss. 100 MHz Bandwidth 4 Channel
