The LeCroy LA314H is a 4-channel analog oscilloscope delivering 470 MHz bandwidth for high-performance signal analysis and troubleshooting across diverse electronic applications. Its high-intensity CRT analog display renders subtle waveform details including gray scaling and persistence effects, making it particularly suited for mixed-signal analysis and low-repetition-rate event capture. The instrument combines ultrafast display update rates with a multipurpose trigger system, broad input offset capability, dual-axis cursors, and an integrated 5-digit frequency counter.
