VIAVI acquired Trilithic in August 2017, in a union of two complementary leaders in test and measurement. Multiple system operators (MSOs) and their contractors can now choose from a wide, unified selection of cable test instruments addressing technologies up to DOCSIS 3.1, and providing the long-term economic benefits of efficiently minimizing leakage in home networks.
Trilithic was founded in 1986 as an engineering and assembly company that built and designed customer-directed products for telecommunications, military, and
industrial customers. From its modest beginnings as a two-man engineering team, Trilithic grew over the years and broadened its offerings of RF and microwave components by adding broadband solutions to its product line. Broadband Instruments and Systems offering test, analysis, and quality management solutions for the major cable television systems worldwide.
Passive intermodulation (PIM) can create interference with cellular communications. It reduces receiver sensitivity or effectively hinders communication entirely. In turn, this affects the signal that the device was making to begin with as well as any receivers nearby.
Though PIM can appear in wireless devices, especially cellular ones, you can conduct PIM testing with the right equipment to mitigate the consequences of PIM.
PIM testing can help you test your cellular device or antenna for any PIM activity, so that you can remedy your signals and have a fully functioning cellular device or antenna.
In this blog, we investigate what causes a PIM and how PIM testing works.
PIM is usually caused when two or more signals are used in passive components in conjunction with some non-linear elements. This causes the signals to interfere with each other and create unwanted signals.
For example, when two cables made from different materials are used, this can cause PIM due to the different material make-up of the cables emitting incompatible signals.
Another factor that causes PIM is the environment in which the device is operating from. If the temperature varies wildly, or if thereís lots of polluted air, the metal components might rust. The environment can also cause the metals around the junctions to have a slightly unstable connection.
While antennas are the go-to areas for PIM testing, you can conduct a PIM test anywhere you think there might be an issue. As a general rule of thumb, PIM issues often appear when the antenna or equipment is installed. However, they also appear if youíre adding new carriers to outdated antenna systems.
There are two popular types of PIM testing methods that you can conduct to check for any PIM or how your antennaís signal performs.
In a reflective or reverse PIM test, you emit two signals to the antenna you want to check. From there, you use the port you sent the signals from to capture and measure any PIM that might appear in your antenna.
Though this method is common in the industry, it needs to be conducted with fixed frequencies, as the electrical length of your antenna can affect the results.
A sweep test is a PIM testing method where you hold a transmit tone fixed in position while changing the frequency of the second transmit tone. This causes the intermodulation (IM) to sweep across different frequencies.
PIMs are the total sum of all the PIM signals that are created on a line at the IM frequency. This means that the sweep test enables you to test the PIM across a range of frequencies, which allows you to paint a picture of the performance of the PIM in your cellular device or antenna.
For a successful PIM test, you must have the right equipment. Here at TMG, we stock a large collection of PIM testing equipment to suit your needs.
The Kaelus External PIM Finder is a compact and convenient solution that can help you identify and locate external PIM sources, such as loose or corroded metals. It quickly supresses the interfering signal with a variety of methods, including removing or covering the PIM source.
