RF interference hunted down in mobile networks

Easy to use, it automatically locates interferers significantly faster than existing solutions on the market by using a real-time FFT receiver and fast automatic direction finding.

The instrument enhances the extensive mobile network testing portfolio from Rohde & Schwarz for interference hunting that includes spectrum analysers, PIM testers, scanning receivers and direction-finding antennas and software.

The wide-ranging RF preselection allows the R&S MNT100 to be used with antennas in dense spectrum environments.

Under such demanding conditions, the locator makes it possible to detect very low-level signals thanks to its exceptionally high spurious-free dynamic range.

It also features the fastest real-time signal processing in its class and, thanks to its fast gap-free realtime FFT, can detect extremely short emissions.

Even signals that are transmitted for 20ns are detected with 100% probability of intercept (depending on signal level).

The instrument’s polychrome display enables resolution of superimposed pulsed signals, making it possible to detect and differentiate complex signal bursts that cannot be seen with traditional swept-tuned spectrum analysers.

Optionally, a handheld dual-mode antenna (R&S HE400CEL) featuring normal or delta mode can be used for accurate manual direction finding.

Adding a magnet-mounted direction-finding antenna with the PC-based R&S MobileLocator software to the RF interference locator enables fast automatic direction finding.

The R&S MNT100 is available in various RF interference locator packages: a standard locator package for manual handheld interference hunting, an automatic locator package for automatic mobile direction finding and the complete locator package comprising basic and automatic locator equipment.
