LeCroy LC334A Oscilloscope, 500MHz, 4 Channel

The LeCroy LC334A is a 4-channel, 500 MHz digital oscilloscope engineered for circuit debug, signal integrity analysis, and embedded systems validation. It delivers 2 GS/s single-shot sampling on the LC334AL variant with up to 8 million points of acquisition memory, enabling capture of complex transient phenomena and sustained waveform characterization across dual channels at maximum sample rate.
