The Fluke 5800A Oscilloscope Calibrator is a precision calibration source designed to verify and calibrate the performance of oscilloscopes across voltage, time, frequency, and impedance parameters. The instrument provides discrete calibration functions including DC and square wave voltage outputs, edge signals for rise time verification, leveled sine waves for bandwidth measurement, time markers for timebase calibration, wave and pulse generators, and oscilloscope input impedance and capacitance measurement capabilities.
Oscilloscope calibrators are used by metrology laboratories, calibration service providers, and instrument manufacturers to verify oscilloscope performance against published specifications. The 5800A supports calibration of oscilloscope voltage accuracy, timebase accuracy, bandwidth and flatness, rise time response, input impedance, and trigger functionality. The included TV trigger signal output with selectable NTSC, SECAM, and PAL-M frame formats supports calibration of oscilloscopes used in broadcast and video applications.
Fluke Corporation, headquartered in Everett, Washington, has manufactured precision electronic test instruments since 1948. Fluke was acquired by Danaher Corporation in 1998 and was subsequently transferred to Fortive Corporation when Danaher spun off its industrial businesses in 2016. The Fluke brand and product lines have remained continuous through these corporate transitions, with calibration and metrology products continuing under the established Fluke name.
