85054B 2-5SpecificationsElectrical SpecificationsElectrical SpecificationsThe electrical specifications in Table 2-3 apply to the devices in your calibration kit whenconnected with a Keysight precision interface.CertificationKeysight Technologies certifies that this product met its published specifications at the time ofshipment from the factory. Keysight further certifies that its calibration measurements aretraceable to the United States National Institute of Standards and Technology (NIST) to theextent allowed by the Institute's calibration facility, and to the calibration facilities of otherInternational Standards Organization members. See “How Keysight Verifies the Devices in ThisKit” on page 4-2 for more information.Table 2-3 Electrical SpecificationsDevice Frequency (GHz) Parameter SpecificationLowband loads DC to 2 Return Loss 48d0.00398)Sliding loads aa. Assuming proper usage, the specifications for the residual return loss after calibration for thesliding load termination include:• the quality of the airline portions within the sliding load, combined with • the effective stability of the sliding element.Proper usage includes the following practices: • Connector mating surfaces are clean.• The changes in slide positioning are NOT done in equal steps since this results in very poorcalibration for some portions of the frequency range.• The center conductor of test port connectors are nominally set back from the outerconductor.Sliding loads are designed to allow the center conductor to be moved. The position of thesliding load center conductor should be set by a reference block and not positioned flushagainst the center conductor of the test port.> 2 to 18 Return Loss 42d0.00794)Adapters(both styles)DC to 8> 8 to  18Return LossReturn Loss34d0.0200)28d0.0398)Offset Opensbb.
