The 5790B AC is a multi-purpose ac measurement and transfer standard that combines the accuracy of a thermal transfer standard with the ease of use of a digital multimeter. Designed for use with the most demanding calibration applications. Absolute ac voltage measurement uncertainties are as low as ± 24 ppm (one year, 23°C ± 5°C).
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. Includes a 6.5 inch touch screen display with graphical user interface which displays specifications for measuring common non-sinusoidal waveforms plus peak-to-peak computation (assumes THD <1 %.).
