Lecroy LC334AM

The Teledyne LeCroy LC334AM is a 500 MHz, 4-channel digital oscilloscope engineered for high-speed signal acquisition and multi-domain analysis. Operating at 2 GS/s per channel with up to 8 Mpts record length, the instrument captures transient events and repetitive signals with 8-bit vertical resolution across a 1 ns/div to 1,000 s/div timebase range. The 9-inch color display (640 x 480 pixels) renders up to eight simultaneous waveforms—channels, memories, or math functions—with Color-Graded and Analog Persistence modes for temporal signal visualization. Sequence mode segments acquisition memory into 2 to 2,000 time-stamped events with 30 µs typical dead time between captures, enabling efficient multi-event characterization. Peak Detect functionality resolves high-speed transients to 2.5 ns resolution. The instrument supports Pattern Triggering across five logic inputs (CH1–CH4 and EXT), width-based triggering from 0.1% duty cycle. Concurrent processing executes up to four math operations (Add, Subtract, Multiply, Divide, Negate, Identity, Summation Averaging, Sine x/x). System architecture includes a 96 MHz PowerPC 603e processor with 8–64 MB RAM supporting rapid waveform calculations and display updates. ProBus input coupling enables automatic probe-type sensing. The instrument operates on 90–132 V AC or 180–250 V AC (45–66 Hz, 400 W) with two-year battery-backed retention of front-panel settings.
