Wavetek's 9500 Oscilloscope Calibration System is truly unique. No other commercially available instrument makes calibrating oscilloscopes so easy. The 9500 System's workload coverage includes analog and digital-storage oscilloscopes with bandwidths up to 1.1 GHz. Its unique active head technology delivers all the necessary calibration waveforms directly to the oscilloscope via a single output connector, and its ability to drive as many as five separate Active Heads eliminates the need for connection lead changes during the calibration process - even on multi-channel oscilloscopes. It's the complete Scope Calibration workstation in a box with everything you need to starting calibrating immediately, including automated software. And there's an option and configuration to suit every Scope Calibration need and budget. Choose from 400 MHz, single channel, to 1.1 GHz and beyond, multi-channel - with full upgradeability between configurations.
