20、imens The close fitting brass tubing shall be machined to thread into connector in lieu of compression nut or any device, which insure the coaxial braid connection. This test set-up between 500 MHz and 11 GHz shall have a dynamic range from 20 dBm to 100 dBm. Using an additional RF source amplifier
21、(e.g. 20 dB), increase total dynamic range. The shorting plunger is adjusted to produce a maximum reading in the detector with the triaxial assembly inserted. 5 Method The insertion loss caused by the insertion of the triaxial assembly adjusted as shown in a measure of total leakage of the mated con
22、nector pair both at its interface as well as the clamping points at both cable ends. The short circuit position is adjusted to assure that adequately low impedance appears behind the equivalent leakage generator. The characteristic impedance of the outer coaxial line of the triaxial system, which is
23、 formed with the inner conductor, should be matched to the detector, 50 coaxial circuits are generally desired for convenience. 6 Results The leakage power ratio is defined as the ratio of the power detected to a detector at the output of the triaxial unit to the power flowing through the internal f
24、lowing power (also through a 50 load). The relative leakage is the ratio: 1221IEZ = where E2is equivalent leakage voltage in external line; I1is the current flowing in internal line. The value must be under the requirement given in the product standard. The insertion loss caused by the insertion of
25、the triaxial assembly adjusted as shown is a measure of the total leakage of the mated connector pair both at its interface as well as at the clamping points to both cables.
