A new type of capacitance standrd based on counting electrons has been built. The operation of the standrd has already given very promising results for the determination of the value of a cryogenic vacuum-gap capacitor. The new capacitance standard operates at an effective frequency close to dc, whereas capacitance metrology usually implies the use of bridges operating at a fixed frequency around 1 kHz. Therefore, the frequency dependence of the cryogenic capacitor is critical to the practical application of this standard. We present measurements of this frequency dependence using a technique that involves the same single electron tunneling devices used in the capacitance standard.
