Brief description

The R&S®MNT100 RF interference locator detects, analyzes and locates even complex pulsed interference signals. With the direction finding (DF) and PC-based radiolocation software upgrade, sources of interference can be located automatically and strikingly faster than with other solutions on the market.

Feature and Benefits

Detects all types of interference

Fast realtime signal processing

Thanks to fast, seamless, realtime fast Fourier transformation (FFT), the R&S®MNT100 does not miss short emissions. Even signals that are transmitted for only 20 ns are detected at 100 % probability of intercept (depending on signal level).The polychrome display allows you to detect and differentiate superimposed pulsed signals that are not visible on traditional swept-tuned spectrum analyzers.

A low-amplitude pulsed signal (Bluetooth®) superimposed by a pulsed signal with higher amplitude (WLAN) can only be seen by using the polychrome display.

Superior RF performance

Exceptionally high spurious-free dynamic range (SFDR) and preselection

The extensive RF preselection allows the R&S®MNT100 to be used with antennas in dense spectrum environments. Under such demanding conditions, the R&S®MNT100 makes it possible to detect very low-level signals thanks to its exceptionally high spurious-free dynamic range. Equipped with a tracking filter and multiple bandpass filters, the R&S®MNT100 suppresses strong out-of-band signals much more effectively than solutions without preselection.

Sophiscated preselection

Accurate manual direction finding

Triangulation of interferers with directional antenna

The desired direction and position information is obtained by manually lining up the R&S®HE400 in the receive direction where the signal is strongest. Several DF results can be combined to perform a triangulation to approximate the position of the signal source on the map display. Optionally, the innovative handheld R&S®HE400CEL dual-mode antenna, which features normal and delta mode, can be used for accurate manual direction finding.

Triangulation based on multiple DF results

Overcome multipath propagation

Fast automatic direction finding with 1° RMS DF accuracy

Adding a magnet-mounted, direction finding antenna to the R&S®MNT100 turns a commercial vehicle into an accurate mobile direction finder within minutes. The R&S®MNT100 uses the correlative interferometer DF method in conjunction with the R&S®ADD207 compact DF antenna. It offers significantly higher DF accuracy of up to 1°RMS.

Others hunt, we locate

Fast automatic location of interferers from a moving vehicle

In order to overcome misleading information from reflections in urban scenarios, up to 600 DF results per minute from the R&S®MNT100 are fed to the R&S®MobileLocator PC-based automatic radiolocation software, which applies sophisticated statistical analysis to discard irrelevant readings and automatically locate sources of interference strikingly faster than other solutions on the market.
