HP / Agilent 54720D 4 channel 8 GSa/s Real-time Modular Oscilloscope Mainframe

The HP/Agilent 54720D is a 4-channel real-time modular oscilloscope mainframe delivering up to 8 GSa/s sampling in single-channel mode. This plug-in architecture supports flexible multi-channel configurations, scaling from 1 channel at 8 GSa/s down to 8 channels at 2 GSa/s. With 2.0 GHz system bandwidth, 8-bit ADC resolution, and up to 65,536 points of acquisition memory per slot (256K with four-wide modules), the 54720D addresses high-speed digital and RF signal capture across research, design validation, and production test environments.
