Assuming proper usage, the specifications for the residual return loss after calibration for the slidingload 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 outer conductor. 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 flush againstthe center conductor of the test port.Return loss 44 dB 0.00631) > 3 to 26.5Offset opens b  0.65 deviation from nominal dc to  3(male and female)  1.20 deviation from nominal > 3 to  8 2.00 deviation from nominal > 8 to  20 2.00 deviation from nominal > 20 to  26.5Offset shorts b  0.50 deviation from nominal dc to  3(male and female)  1.00 deviation from nominal > 3 to  8 1.75 deviation from nominal > 8 to  20 1.75 deviation from nominal > 20 to  26.5Adapters c Return loss 30 dB 0.03162) dc to  8Return loss 28 dB 0.03981) > 8 to  18Return loss 26 dB 0.05012) > 18 to  26.5
