The HP/Agilent 54542C is a 4-channel digitizing oscilloscope delivering 500 MHz analog bandwidth and 2 GSa/s sampling rate per channel for high-fidelity signal acquisition across analog design, R&D, and manufacturing test environments. Its color LCD display, 32K-point acquisition memory per channel, and 1 ns peak detect capability enable capture and visualization of narrow transient events. The instrument combines sophisticated triggering—including logic, glitch (1 ns minimum), and TV triggering—with independent control of sample rate and record length, decoupled from sweep speed. Sequential single-shot acquisition eliminates dead time between successive events, benefiting pulsed-laser research and pulse-echo applications. Pre-trigger viewing captures signal behavior before the trigger point. Software-selectable input impedance (50 Ω or 1 MΩ) accommodates both RF and general-purpose measurements. Standard FFT delivers spectral analysis directly on acquired waveforms.
