  • Page 4: General Information And Safety Instructions

    If personal safety gear is required in order to use the Rosenberger PIM Rack Analyzer, this will be indicated at the appropriate place in the product documentation. Keep the basic safety instructions and the product documentation in a safe place and pass them on to any subsequent users.
  • Page 5 PIM Rack Analyzer Manual • Never switch output power on (in manual mode or remote mode) without a load or terminated OUT connected to the test port. • Unless otherwise specified, the following requirements apply to this product: IP protection 2X, pollution severity 2, overvoltage category 2, max.
  • Page 6 • Operation of the PIM Rack Analyzer can produce electromagnetic radiation. Ensure that the radiation levels do not exceed the limits stipulated by national regulations. Persons with pacemakers and pregnant women are especially at risk.
  • Page 7 Adjustments, replacement of parts, maintenance and repairs may only be performed by electrical experts authorized by Rosenberger. Only original parts can be used for replacing safety parts (e.g. power switches, power transformers, fuses). A safety test must always be performed after safety parts have been replaced (visual inspection, PG conductor test, insulation resistance measurement, leakage current measurement, functional test).

    Measuring PIM with swept carrier frequencies. Allows detection of multiple PIM sources in the signal path. An unsteady graph would indicate that more than one PIM source is present because all reflected PIM waves would interfere posi- tively and negatively over frequency.

  • Page 31: Dtf

    Measuring the distance to the PIM fault and return loss fault position. The graph plots the PIM and RL values over distance, so even multiple sources can be detected and the level measured. The velocity factor has to be known for accu- rate display scaling.

  • Page 32: Isolation

    Measuring the isolation between separate RF paths (e.g. decoupling of two an- tennas or separate polarizations). For this purpose, a signal is transmitted from the PIM measuring port (7-16 or 4.3-10) and the leakage is received at the N- connector.

  • Page 33: Power Sweep

    Manual 5.8 Power Sweep Measuring PIM as a function of power to the DUT. Because PIM is an extremely nonlinear effect with many causes, it is hard to predict the power level at which PIM will start to rise. PIM sources or measurement headroom can be identified in this manner.

  • Page 34: Spectrum Analyzer

    Measuring the uplink spectrum prior to PIM measurements is useful to detect if interferences (e.g. mobile devices transmitting unintentionally) are disturbing the PIM measurement. The RF power density on the graph shows if there are static signals which must be ignored on PIM measurements.

  • Page 35: Common Settings

    It is advisable to keep loss. on the screen “Check RL before PIM measurements” activated – it protects the unit from excessive VSWR and device damage caused by hot plugging.
