1. When using slotted connectors inspect the contact fingers in the female center conductor carefully These can be bent or broken and damage to them is not always easy to see A connector with damaged contact fingers will not make good electrical contact and must be replaced NOTE This is particularly important when mating nonprecision to precision devices Precision Slotless Connectors 2 4 mm The female 2 4 mm connectors in this set are metrology grade precision slotless connectors PSC Precision slotless connectors are used to improve accuracy A characteristic of metrology grade connectors is directly traceability to national measurement standards through their well defined mechanical dimensions With PSCs on test ports and standards the accuracy achieved when measuring at 50 dB return loss levels is comparable to using conventional slotted connectors measuring devices having only 30 dB return loss This represents an accuracy improvement of about 10 times The female 2 92 mm connectors have slotted contacts and therefore cannot be considered metrology grade Due to the extremely thin wall of the 2 92 mm female connector a slotless metrology grade 2 92 mm connector pair does not currently exist Conventional female center conductors are slotted and when mated are flared by the male pin Because physical dimensions determine connector impedance this change in physical dimension affects electrical performance making it very diffi
