HP / Agilent 54620C Color 16 Channel Logic Analyzer

The HP/Agilent 54620C is a 16-channel logic analyzer built around a color active matrix LCD display and scope-like control interface for intuitive digital signal capture and analysis. Operating at 500 MSa/s with configurable record lengths up to 8K samples, it delivers fast signal acquisition paired with automatic glitch detection down to 3.5 ns. Advanced triggering—edge, pattern, and dual-term logic with operators including Or, Then, Duration, and N-occurrence counting—enables capture of complex digital events. The timebase spans 5 ns/div to 1 s/div with 0.01% accuracy, supporting both main and delayed sweeps. Cursor-based measurements extract frequency, period, duty cycle, setup/hold time, and signal delays, with readout in hexadecimal or binary notation. Sixteen front-panel setups store configuration and trigger states in non-volatile memory, while dual volatile pixel memories preserve waveform displays for comparison. Channel labeling from a library of 75 presets plus user definitions streamlines multi-signal interpretation. The analyzer accepts all 16 channels or external trigger inputs and operates in Auto or Normal trigger modes. Timebase cursor accuracy reaches ±(sample period + 0.01% of reading + 0.2% of screen width) for single-channel measurements, with dual-channel accuracy accounting for channel-to-channel skew. Compliance with CISPR 11 Class A and EC EMC Directive 89/336/EEC ensures reliable operation in industrial and laboratory environments.
