Output Noise Considerations

Any noise picked up on the sense leads will appear at the output terminals and may adversely affect
CV load regulation. Twist the sense leads or use a ribbon cable to minimize the pickup of external
noise. In extremely noisy environments it may be necessary to shield the sense leads. Ground the
shield at the power analyzer end only; do not use the shield as one of the sensing conductors.
The noise specifications documented in the Keysight N6700 Modular Power System Family
Specifications Guide apply at the output terminals when using local sensing. However, voltage
transients may be produced at the load by noise induced in the leads or by load current transients
acting on the inductance and resistance of the load lead. If it is desirable to keep voltage transient
levels to a minimum, place an aluminum or tantalum capacitor, with an approximate value of 10 µF per
foot (30.5 cm) of load lead, right across the load.
