The Fluke Model 5200A AC Calibrator is a precision high-performance AC voltage source with proven reliability and exceptional stability and accuracy over a broad frequency range. Wide output range & lab standard accuracy makes this instrument useful in both laboratory and manufacturing environments. Outputs from 100 µV RMS to 120 V RMS at a 50 mA current level. Frequency range from 10Hz to 1.2MHz with accuracy of ±(1.0% + 0.1%). Amplitude range is 1 mV to 1000 V in seven ranges. 6-digit resolution, yielding 1 nV steps on the 1 mV range increasing to 1 mV steps on the 1000 V range, with an error measurement provided in two ranges (±3% or ±0.3%). 20% overrange capability. Amplitudes of 100 V to 1000 V are only available when used with the Fluke Model 5205A or 5215A Amplifiers.
