Lecroy SDA100G

The Teledyne LeCroy SDA 100G is a Near Real Time Oscilloscope (NRO) that combines sampling oscilloscope bandwidth with real-time instrument speed and flexibility. It delivers 100 GHz bandwidth with 10 MSa/sec acquisition rate and up to 48 Mpts of standard memory, expandable to 2G samples per channel for extended serial data pattern capture. The instrument leverages Accelerated Throughput Architecture (ATA) to achieve acquisition speeds 100 times faster than conventional sampling scopes, and Coherent Interleaved Sampling (CIS) to phase-lock the sample clock to the input signal’s bit rate—enabling long waveform analysis without external pattern triggers. Random Interleaved Sampling (RIS) measures pulsed signals without external trigger requirements.
