21、E DEVICES, INTERMODULATION LEVEL MEASUREMENT Part 3: Measurement of passive intermodulation in coaxial connectors 1 Scope This part of IEC 62037 defines the impact test on coaxial connectors to evaluate their robustness against weak connections and particles inside the connector as independently as
22、possible from the effects of cable PIM (passive intermodulation). For other connectors (e.g. panel mounted connectors), the cable can be replaced by an adequate transmission-line (e.g. airline, stripline). In order to evaluate the effects of mechanical stresses on the connectors, a series of impacts
23、 is applied to the connectors while measuring the PIM. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest

BS EN 62037-3:2012 6 62037-3 IEC:2012(E) a) Setup 1 Multi-port DUT In order to minimize the effect of the transmission line, a short assembly should be tested. Identical connectors should be assembled to each end. An assembly, as short as phy
27、sically practical, should be constructed. b) Setup 2 One port DUT A single connector can be assembled on a length of transmission line for which it is designed, loss or low loss, that exhibits at least 10 dB of attenuation in one direction at the lowest frequency in the receive band. 4.2 Connection
28、of unit The unit should be connected as described in the IEC 62307-1 base document. 4.3 Setup 1 Fixed frequency test considerations Due to the phase interaction of the connectors and the length of the transmission line (configuration A) when measured in the reverse (reflected) mode, the frequency at
29、 which maximum PIM occurs within the band can vary and shall be determined. An accepted method of sweeping is to fix F1 at the low end of the transmit band and step F2 down, starting at the top of the band for all combination of frequencies that result in IM in the receive band. If desired, this pro
30、cedure can be reversed by fixing F1 at the highest frequency in the transmit band and then stepping F2 up, starting at the bottom of the band. If fixed frequency is used, assemblies of varying lengths shall be made to ensure that the PIM adds in-phase. Assemble 2 additional DUTs. The first one is to
31、 be /6 longer and the second one is to be /3 longer at the receive frequency of test. The PIM of the three (3) assemblies is measured to determine which DUT exhibits maximum PIM. The impact test shall be performed on this DUT. Multiple fixed frequency may be used in lieu of varying the cable length.
32、 The impact test is to be conducted at the frequency where the maximum PIM is measured. The cable used as a load should be verified as having suitable PIM performance prior to being used in testing as measured by IEC 62037-4. 4.4 Setup 2 considerations The cable used as a load should be verified as
33、having suitable PIM performance prior to being used in testing as measured by IEC 62037-4. 4.5 Impacts Mount the DUT as shown in Figure 1. A minimum of five (5) impacts in accordance with Table 1 should be applied. (See Figure 1 for impact setup and Figure 2 for description of drop mass and tube.) T
34、he tube should be vertical to the axis of the DUT to 3. The points of impact should cover as many different areas along the length of the connector as possible, but it is not necessary to rotate or otherwise disconnect and reposition the DUT. The PIM is measured prior to, during, and after the impac
