■High-accuracy AC voltage/current measurement
The 5790B is designed for use in a wide variety of applications required in everyday calibration tasks, and combines the high accuracy of thermal transfer standards with the ease of use of a digital multimeter. It is a measurement standard. Uncertainty in absolute AC voltage measurements is as low as ± 24 ppm (1 year, 23°C ± 5°C).
5790B is a multi-function calibrator 5730A, 5720A and 5700A, multi-product calibrator 5522A, 5502A, 5520A, 5500A and other calibrators, 52 Designed to meet the complete AC voltage and broadband verification requirements of amplifiers such as 120A, 5725A, 5205A/5215A, as well as transfer standards and AC voltmeters. (5720A, 5700A, 5520A, 5500A, 5205A/5215A are discontinued)
The 5790B has an AC voltage range of 600 μV to 1000 V and a frequency range of 10 Hz to 1 MHz. Wideband voltage options extend the frequency range to 30MHz or 50MHz. The 5790B is also compatible with the Fluke A40B current shunt, allowing direct, absolute or relative current measurements without calculations.
The 5790B can be used alone or as a transfer standard for external AC/DC sources. In either case, the tedious switching and calculations are automatically performed by the 5790B, and the resulting AC/DC difference is displayed directly on the easy-to-read 6.5-inch color touchscreen display.
