The HP 54201A and HP 54201D Digitizing Oscilloscopes are dedicated, two-channel, simultaneous, waveform acquiring digital storage oscilloscopes with full HP-IB programmability, digitized waveform data output, and resident parametric waveform measurements. HP 54201 A/D - General Information The HP 54201 A/D is a general purpose digitizing oscilloscope with 300 MHz repetitive bandwidth and a single-shot digital storage bandwidth of 50 MHz (200 rneqasamples/second) with infinite store time and waveform data output. It also provides parametric information about the analog characteristics of waveforms. The HP 54201 D has all the features of the HP 54201A with the addition of parallel and serial logic trigger qualification capabilities. The HP 54201 D includes 3 pods, each containing 8 bit + 1 parity bit + clock organization. The key features of the HP 54201 A/D Digitizing Oscilloscopes are: • 300 MHz repetitive bandwidth with ±200 ps time-interval accuracy. • 200 rneqasarnples/second sample rate, 50 MHz single-shot bandwidth using post capture data interpolation. • Capture two channels simultaneously. • Holdott-by-events to trigger acquisition after a specified number of events. • Pre-trigger viewing. • All front panel controllable parameters can be programmed via HP-IB. • Continuously updated automatic waveform parameter measurements with user-defined thresholds. • Waveform math: Ch1 +Ch2 and Ch1-Ch2. • Set up aids such as automatic waveform scaling, ECl/TTl preset levels, and save/recall of front-panel setups. • One button hardcopy to HP-IB printers and plotters. • Digital logic trigger qualification (HP 54201 D only).
