The Teledyne LeCroy LC564A is a 1 GHz, 4-channel digital oscilloscope built for precision waveform acquisition in research, design verification, and field troubleshooting. It delivers single-shot sampling to 4 GS/s and Random Interleaved Sampling (RIS) to 25 GS/s for repetitive signals, with flexible memory allocation up to 500 kpts per channel. The instrument combines advanced trigger capabilities—including glitch detection at 600 ps and SMART trigger modes with exclusion technology—with comprehensive math, spectrum, and parameter analysis functions. An 8-bit vertical system spans 2 mV/div to 1 V/div with ±20 V offset range, DC accuracy of ±(2% full scale + 1% offset), and selectable bandwidth limiting at 25 MHz or 200 MHz. The color 10.4-inch TFT display (640 × 480 pixels) and 96 MHz PowerPC processor enable real-time Analog Persistence mode and simultaneous multi-function processing. GPIB connectivity and onboard storage via floppy disk support integration into automated test environments. Maximum input voltage ratings reach 100 V (1 MΩ) or ±5 VDC (50 Ω), with external trigger capability to 750 MHz.
