AC/DC high frequency measurement (up to 1V 100MHz)

AC DC high frequency measurement 1 AC DC high frequency measurement 2 AC DC high frequency measurement 3 

As industry has expanded the frequency range of their AC sources / measuring systems, NPL has a UKAS accredited service that can calibrate customers measuring systems, e.g. 5790's, 4920's up to 100 MHz, currently at voltages from 0.5 to 1V.

Typical uncertainties quoted are from 51 ppm (3 MHz) to 0.21% (100 MHz).

See AC/DC voltage and current transfer for information on AC/DC Transfer.
