- Portable Analyzers Hunt For Interference
- Identifying Interference
This line of portable spectrum analyzers, when equipped with an additional interference-finding system, can detect and identify RF/microwave interference sources in the field.
To assist with the difficult task of isolating interference sources, the MA2700A InterferenceHunter™ was developed for use with the Spectrum Master handheld analyzers, as well as with the company’s BTS Master™ and Cell Master™ handheld analyzers for cellular communications systems (it works with any of the analyzers equipped with the Interference Analysis option). The MA2700A InterferenceHunter is a handheld direction-finding (DF) subsystem that works with any of the handheld analyzers.
The MA2700A InterferenceHunter is effective at spectrum clearing and interference tracking, as well as when installing, deploying, and maintaining wireless networks. It incorporates a Global Positioning System (GPS) receiver and antenna, an electronic compass, and a user-selectable preamplifier. It connects to the analyzer by means of a Universal Serial Bus (USB) cable and requires no additional power source.
When armed with this subsystem, one of the MS2720T analyzers becomes a powerful interference detection and tracking tool. For an area of interest, a map can be stored within the analyzer. Once an interference signal has been detected, the MA2700A InterferenceHunter allows an operator to draw a vector line to the interfering source on the map. Operators can zoom on a section of the map to facilitate a search for an interference source.
The Spectrum Master MS2720T series analyzers are built for the field, in durable housings that weigh between 9.7 and 10.7 lbs (4.4 to 4.9 kg), depending upon model and options. All of the MS2720T series analyzers measure 12.4 x 8.4 x 3.7 in. (315 x 211 x 94 mm). To aid in the process of locating and identifying interference, Anritsu offers a 20-page application note, “RF Interference Hunting Techniques.” This document offers helpful guidance not only on spotting interference, but also on resolving the problems caused by it. P&A: $2600 (MA2700A InterferenceHunter); 4 to 6 wks.
