Evaluation of the calculable high frequency ac/dc standard

The calculable HF ac/dc transfer standard has been developed at VSL. An improved model which contains a more detailed description of the thermal element with the end disc and the housing, is presented together with measurements. The major result is a calculated shift of about 4000 ppm in the ac/dc d...

Beschreibung
Zusammenfassung:The calculable HF ac/dc transfer standard has been developed at VSL. An improved model which contains a more detailed description of the thermal element with the end disc and the housing, is presented together with measurements. The major result is a calculated shift of about 4000 ppm in the ac/dc difference at 100 MHz. Based on this model, a 2 V standard is under development.
