Advantages of PIM Analyzer | disadvantages of PIM Analyzer
This page covers advantages and disadvantages of PIM Analyzer. It mentions PIM Analyzer advantages or benefits and PIM Analyzer disadvantages or drawbacks.
PIM stands for Passive Intermodulation. The device used to test PIM related measurements to comply with IEC 62037 which is industry recognised specification. It can be used to perform various PIM measurements viz. PIM vs time, distance to PIM, swept PIM and noise floor. It is used to certify cables and antennas. It can also perform other RF and microwave measurements such as return loss, VSWR, cable loss, distance to fault, smith chart, 1-port phase etc.
The figure-1 depicts PIM products generated due to active and passive components
in a microwave circuit. PIM analyzers from leading companies such as Anritsu and Rosenberger
support various frequency bands covering technologies such as E-GSM, LTE, UMTS, PCS, DCS etc.
