Lecroy 7242

The LeCroy 7242 is a dual-channel plug-in module for the LeCroy 7200 and 7200A Series Modular Oscilloscope mainframes. This acquisition module delivers 400 MHz bandwidth at 50Ω input impedance and 250 MHz at 1M� impedance, with selectable input options on screen. Single-shot sampling reaches 1 GS/s across both channels, while repetitive sampling extends to 20 GS/s for time-correlated acquisitions. The module stores up to 50k points per channel and accepts input signals from 5 mV/div to 1 V/div with maximum ratings of ±5 V DC (50Ω) or 5 Vrms. Variants 7242A and 7242B offer extended memory and configuration options for specialized measurement requirements.
