C1 – 1μF X7R multilayer ceramic capacitor rated at minimum 3 x the output voltage of the UUT C2 – 10μF tantalum capacitor rated at minimum 1.5 x the output voltage of the UUT with ESR of less than 100 milliohms at 100 kHz e.g. AVX TPS series. C3 – 100nF multilayer ceramic capacitor, general purpose R1 – 450 Ohm resistor, carbon film, ±1% R2 – 50 Ohm BNC termination T1 – 3T of the coax cable through a ferrite toroid eg Ferroxcube TN32/19/13-3E25 RLOAD – Resistive load at the UUT maximum rating. Connections via twisted wires.
