WebPIM testing is a measure of linearity within a cellular transmission system. It is a very comprehensive test of mechanical integrity. Two high power test signals are injected into the antenna line. If any corroded, dirty or mechanically compromised connections or components exist, the two test signals will mix and produce intermodulation. WebPIM test 4 high-band ports, 3 different bands simultaneously in one connection Overall test time ~ 30 seconds in sweep mode (PIM test including cable connection) Benefits Reduce test time and connection cycles Improve testing efficiency Optimize utilization of test equipment (totex) Reduce complexity of test setup Minimal cabling required WebAug 3, 2024 · The PIM analyzer transmits high power; therefore, before PIM testing, any high-power reflection, for example, generated by a pinched cable, must be located and repaired. Return loss can be easily measured over a wide frequency range with a cable and antenna analyzer such as the R&S®Cable Rider ZPH or the R&S®ZVH. incipient crossword

WebAn antenna reflector is a device that reflects electromagnetic waves. Antenna reflectors can exist as a standalone device for redirecting radio frequency (RF) energy, or can be integrated as part of an antenna assembly. WebFigure 1: PIM vs. Test Power for a variety of objects. Looking at the data in figure 1, it is interesting to note that the change in PIM level vs. power for each device is nearly constant over the range of powers tested. For every 1 dB change in test power, the PIM level changes by a fixed number of dB.
