Analyzer Anritsu PIM Master MW82119B allows you to identify sources of passive intermodulation distortion (PIM) inside the antenna-feeder path of the mobile network infrastructure, as well as outside it - in the immediate vicinity of the transmitting antennas. PIM measurement is an important part of the quality assurance of existing 3G networks. And when deploying 4G and 5G networks, which use large channel widths and complex modulation types, measuring and minimizing the PIM level is absolutely necessary. The portable Anritsu PIM Master MW82119B is specially designed to effectively solve this problem. You can download a full description of all the characteristics of Anritsu MW82119B below on this page in the section Documentation.

The signal emitted by a mobile communication antenna has a power of several tens of watts, and the width of its spectrum for 4G and 5G networks is several tens of MHz. When this signal passes through the antenna-feeder path and further on the air, it encounters various inhomogeneities, which can lead to multiplication of the frequency components of the signal and the formation of additional frequencies. This effect is called passive intermodulation (PIM for short). Within the AFU, PIM sources can be: corroded connectors, poorly tightened connectors, gas dischargers, filters, the feeder itself, an antenna, etc. Outside the AFU, any metal object located in the radio signal radiation zone of the antenna can become a PIM generating source. Particularly strong intermodulation products are generated on large metal objects,

Why has so much attention been paid to the PIM effect lately? One of the reasons is that the frequency of the intermodulation products very often falls into the uplink range, which leads to a significant degradation of the coverage area, a decrease in the data rate and disconnections. Therefore, along with the usual measurements of the SWR of the feeder and the distance to the heterogeneity according to the SWR in the feeder, which have long been standard, it is also necessary to measure the PIM level and the distance to the heterogeneity according to the PIM.

Intermodulation sources can be located both inside the AFU and outside it.
Intermodulation sources can be located both inside the AFU and outside it.


The PIM Master MW82119B analyzer belongs to the third generation of measuring instruments of this class from the Japanese company Anritsu. This analyzer allows you to completely solve the problem of finding and eliminating PIM sources in mobile communication systems. It also allows you to measure SWR, power, feeder losses and determine the distance to inhomogeneities in the feeder. That is, it contains in a compact, dust-proof, moisture-proof case all the necessary tools to optimize the site.

Track PIM level changes over time

The basic measurement that is carried out at the facility is the measurement of the PIM level over a period of time. It can be used to determine the stability of the system and identify the sources of short-term generation of PIM. During this test, the Anritsu MW82119B repeatedly feeds two carriers into the feeder and measures the third, fifth, or seventh order intermodulation power, plotting the measured value. The test usually takes a few minutes. Tapping of suspicious feeder sections can be used, since PIM often occurs in places affected by corrosion, and they usually change their properties under mechanical stress.

In this screenshot of the Anritsu PIM Master MW82119B analyzer, a PIM power measurement is performed over a 30 second time period. As shown at the bottom of the analyzer screen, it generates two carriers: 935 MHz and 960 MHz, 20 W each. At these carrier frequencies, the third order intermodulation product is located at 910 MHz. For most of the test, the power of this component was at the level of -119 dBm, but several times it jumped to values of about -90 dBm. As you can see, this type of test is well suited for assessing the stability of the PIM level over time.

Determination of distances to PIM sources

The main task of the Anritsu MW82119B analyzer is to identify all sources of passive intermodulation that may interfere with the normal operation of the base station. And Anritsu PIM Master copes with this task in the best way. In addition to displaying a distance plot to PIM sources (called DTP), the MW82119B shows the exact location of these sources, allowing them to be located with a resolution of up to 10 cm.

This screenshot shows how the Anritsu MW82119B analyzer automatically detected the presence of three PIM sources and placed three vertical red markers on the graph in the places of their detection at distances: 0.7 meters, 15.2 meters and 19.7 meters.

Measuring the level of interference at the frequency of the intermodulation component

This test determines the presence and level of interference at the frequency of the intermodulation product of interest. This test is necessary because nearby mobile phones and other radio transmitting devices can cause significant interference at exactly the frequency of the intermodulation product that you want to measure. When there are no interfering transmitters nearby, the power level recorded in the Noise Floor mode is about -120 dBm or even less.

This screenshot shows the screen of the Anritsu MW82119B analyzer when checking the noise level at a frequency of 910 MHz. During this measurement, the MW82119B does not apply two-carrier power to the feeder, but simply measures the interference level at a user-specified intermode frequency (3rd, 5th, or 7th).

And this screenshot shows the screen of the Anritsu MW82119B analyzer in the presence of interference at a frequency of 910 MHz. The horizontal green line is set to -97 dBm, which is defined as the limit in this case. In such an interference environment, accurate PIM measurements cannot be made. The solution may be to slightly change the frequencies of the Frequency 1 and Frequency 2 generation, which will cause a corresponding shift in the frequencies of the intermodulation products. The second solution is to temporarily disable interfering radio transmitters.

Additional features and measurement modes of the Anritsu PIM Master MW82119B analyzer

The main feature of the Anritsu solution is that the MW82119B analyzer is able to find PIM sources not only inside the antenna-feeder path, but also outside it. Over the years of the struggle of mobile operators with the problem of PIM around the world, exhaustive statistics have accumulated. As practice shows, more than half of all significant PIM sources are outside the AFU in the area of the antenna radiation pattern. These can be metal mounting structures, rusty tin on roofs, and even reinforcement inside reinforced concrete floors. With the Anritsu MW82119B analyzer, you can find all these sources and take the necessary measures, such as antenna reorientation or shielding.

Separately, it is worth noting the presence of a full-fledged built-in AFU analyzer, similar in capabilities to the device Anritsu S331E. This functionality, added with option 0331, allows you to not only measure feeder SWR, cable loss and other standard functions, but to superimpose the DTP (distance to PIM) trace over the DTF (distance to discontinuity) trace, which opens up new opportunities for optimizing equipment performance.
