LeCroy LP142 100 MHz, Digital Storage Oscilloscope

The LeCroy LP142 is a 100 MHz digital storage oscilloscope built for signal analysis, waveform capture, and circuit debugging. Featuring dual channels, 500 MS/s real-time sampling, and 25 GS/s equivalent sampling capability, this portable instrument delivers 8-bit vertical resolution across a 5.8-inch LCD display. The LP142 supports vertical sensitivity from 2 mV/div to 10 V/div, accepts input voltages to ±400 V (DC+ACpeak), and includes selectable bandwidth limiting (DC to 10 MHz). Its comprehensive triggering system—edge, event, and TV modes with polarity selection and count/burst/missing event detection—enables reliable capture of complex signals. With 13 automatic measurements, hardware five-digit frequency counter, and cursor-based voltage and time analysis, the LP142 provides engineering-grade diagnostics. A 5.8-inch blue LCD with Y-T and X-Y display modes supports both real-time and offline analysis. The instrument integrates remote control via RS-232C and GPIB, with automatic waveform output to printers, ATA cards, or floppy media. Weighing 3 kg and measuring 215 mm × 170 mm × 166 mm, it operates across 0°C to 40°C and reaches full accuracy after 30 minutes warm-up. Power consumption reaches 90 VA maximum with integral printer operation, drawing from 100–240 VAC, 50/60 Hz sources. Horizontal timing accuracy is 50 ppm; vertical accuracy is ±2%. The LP142 serves electronics testing, educational laboratories, and field service applications where bandwidth and portability balance operational demands.
