The HP 54505B is a 300 MHz, 500 MSa/s sample rate, 2-channel digitizing oscilloscope. Use it to trigger on a wide variety of user-specified conditions. Trigger on edge, pattern, state, or trigger after delay to capture such elusive events as timing violations or transient bus phenomena. To pinpoint infrequent events and determine their cause, use HP's advanced logic triggering in conjunction with up to four channels to quickly isolate anomalies. Triggering on an anomaly will allow you to probe other points within the system during the failure condition to understand the cause of tbe problem quickly. If you are characterizing several events separated in time, the sequential single-shot capability allows you to capture the pulses without dead time in between. You can then analyze the pulses individually or all together in normal, averaged, or envelope mode. Specifications. Repetitive Bandwidth: 300 MHz (equivalent time). Number of channels (simultaneous acquisition): 2. Vertical sensitivity range: 1 mV/div to 5 V/div. Vertical dc gain Accuracy: ± 1.25% of full scale. Vertical resolution: 8 bits (10 bits via HP-IB with averaging). Maximum sample rate (Real time mode): 500 MSa/s on all channels). Waveform record length: 8001 points (real-time), 501 points (repetitive). Maximum input: 1 M-ohm: ± 250 V [dc + peak ac < 10kHz)], 50 ohm: 5 V rms. Time base range: 1 ns/div to 5 s/div.
