Product Highlights

the 5790B AC Measurement Standard is a multi-purpose ac measurement and transfer standard designed for the most demanding calibration applications. It combines the accuracy you would expect from a thermal transfer standard with the ease of use of a digital multimeter. Absolute ac voltage measurement uncertainties are as low as ± 24 ppm (one year, 23 °C ± 5 °C). The 5790B is designed to meet the complete ac voltage, ac current and wideband verification requirements of the fluke Calibration 5735A, 5720A, and 5700A Multifunction Calibrators; 5522A, 5502A, 5520A, and 5500A Multi-Product Calibrators; plus other calibrators, amplifiers like the 52120, 5725A and 5205A/5215A, and transfer standards and ac voltmeters.

The 5790B covers an alternating voltage range of 600 µV to 1000 V, and a frequency range of 10 Hz to 1 MHz. Wideband voltage options extend frequency range to 30 or 50 MHz.

The 5790B in combination with the fluke A40B Current Shunts now allow you to make direct, absolute or relative current measurements without the need to perform any calculations.

The 5790B may be used alone as a measurement device or as a transfer standard when compared to an external dc source. In either case the normally tedious switching and calculations are performed automatically by the 5790B, and the resulting ac/dc difference is displayed directly on the easy-to-read 6.5-inch full-color capacitive touch screen display.

Confidence level 99% unless otherwise specified
  The 5790B/Af has enhanced absolute accuracy to ± 0.23 % of voltage (1 year after factory calibration, 23 °C ± 3 °C, at 95 % confidence level) at 50 MHz and 223.61 mV, using a serialized one meter cable, characterized at that point for Rf power meter 0 dBm reference output measurement. In the Rf power measurement mode, the accuracy is specified to the end of the serialized cable with a curve fit for the other ranges and frequencies that is a first order correction for cable loss.
