The HP/Agilent 54600B is a dual-channel, 100 MHz analog oscilloscope built for production testing, field service, and educational applications. This instrument delivers 20 MSa/s maximum sample rate with 4,000-point record length and real-time vector display capability. Channel sensitivity spans 2 mV/div to 5 V/div with ±2% DC gain accuracy. The 5 ns/div to 5 s/div timebase supports horizontal accuracy of ±0.01% and 100 ps resolution. Peak detect captures glitches as narrow as 50 ns. Four trigger modes—Auto Level, Auto, Normal, and Single—with selectable sources (CH 1, CH 2, Line, External) enable flexible signal capture. Dual cursors with user-configurable thresholds support automatic voltage and time measurements including frequency, period, rise/fall time, and duty cycle. Setup storage preserves up to 16 front-panel configurations. Negative time viewing, waveform storage, and automatic setup accelerate troubleshooting workflows. The instrument weighs under 15 pounds in a compact, lightweight form factor.
