Peak-to-peak and RMS metering equipment must have Construction a 20 MHz frequency response with probes and cables A=Open PCB that maintain a frequency response of 20 Hz to 20 MHz. Output Voltage Output ripple and spikes are measured directly at the (Model) output terminals of the power supply with a 0.1 µF ceramic capacitor. The probe ground band must make direct contact with the output return or common terminal load. With multiple output models, the output under test is brought to 60% of nominal load; to prevent erroneous noise measurements. load current is then varied +40%/-30% of nominal while other outputs are held at nominal 6.
