The LeCroy 9450 is a dual-channel digital oscilloscope delivering 300 MHz bandwidth with sampling rates up to 400 MS/s for transient capture and 10 GS/s for repetitive waveforms via random interleaved sampling. The instrument combines 8-bit vertical resolution, extended memory segmentation, and sophisticated triggering architecture to support signal acquisition and analysis across telecommunications, electronic design, laser systems, computer hardware, non-destructive testing, and defense applications.
