Amplitude calibrator for oscilloscopes
Abstract
The amplitude calibrator is designed to provide known dc voltage levels or 1 kHz square waves from plus or minus 1 mV to plus or minus 5 V. It features selectable output impedances of less than 0.1 ohms, 50 ohms, and 1 M ohms. The instrument is designed with sufficient current capability to deliver its indicated voltage into a 50 ohms termination. To protect delicate sampling oscilloscopes, a limiter circuit can also be activated to limit the output voltage to plus or minus 1.8 V.
