Pim Measurement Procedure

Passive intermodulation pim is a form of intermodulation distortion that occurs in passive components such as antennas cables connectors or duplexers with two or more high power input signals.

Pim measurement procedure.

Our test and measurement portfolio includes cable and antenna analyzers and pim test equipment.

The pim test is a measure of system linearity while a return loss measurement is concerned with impedance changes. Re measure dtp on the antenna system with the strong pim source removed.

Kaelus test and measurement products are used in design manufacturing and rf wireless solutions. Passive intermodulation pim measurement. Kaelus also offers pim training and pim certification courses. Test and measurement solutions.

Measurements pim tests conducted on four different objects with the test power varied between 2 5w 34 dbm and 40w 46 dbm. The pim master will overlay the active trace site pim with the stored trace pim marker and automatically insert a delta marker showing the relative distance between the two dtp peaks. Kaelus offers 2 series of portable pim analyzers and a full line of pim testing accessories. The pim source at least 3 m behind or below the antenna.

The ipa pim analyzer a light weight battery powered unit is the most popular pim testing analyzer on the market as well as the 40w ipa series used primarily in external pim testing. The objects include two rf cables a coupler and the pim analyzer itself. Further details on the use of personal data and the withdrawal procedure are set out in. An easier way to accomplish this is by using the pimpoint tool or distance to pim measurement available on the pimpro tower.

Impact of test frequency selection on the magnitude of pim produced procedures for testing sites with frequency limiting components moderator. This measurement process tests real world pim scenarios such as self generated pim caused when multiple 15 khz subcarriers making up the lte signal mix and create intermodulation as well as 2nd and 3rd order harmonics e g 850 mhz downlink interfering with the 1700 2100 aws uplink or the 900 downlink interfering with the 1800 2100 uplink. Pim in the transmission path degrades quality of the wireless communication system. Jeff mucci ceo and editorial director rcr wireless.
