We present the first steps taken towards a graphene quantum Hall effect ac resistance standard at RISE. A new measurement setup has been developed including a graphene quantum Hall effect device suitable for the kilohertz range and a coaxial cryoprobe to be used together with a coaxial impedance bridge based on inductive voltage dividers. 1:1 ratio resistance measurements of the graphene device against a 12.9 kΩ ac resistance standard resulted in a linear frequency dependent (≈ 0.2(μΩ/Ω)/kHz) deviation from the quantized dc value.
