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 the frequency range to 30 or 50 MHz.
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.
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.
5790B AC Measurement Standard

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. |
