High total field strength of ≥ 1 V/m peak envelope power (PEP) at radar antenna 200 m away

Brief Description

The R&S^®TS6650 detects potential interference to air traffic control (ATC) radar systems caused by LTE and WiMAX^™ emissions in the adjacent frequency band.

Features

Realistic, adaptable scenarios
Complete radar test in normal operating mode
Modular, future-ready system concept

Specifications

Frequency range	2500 MHz to 2690 MHz
ATC radar frequency range	2720 MHz to 3100 MHz
Test distance	100 m to 300 m

Key Facts

Verification of immunity using realistic scenarios involving multiple LTE and WiMAX^™ emitters
High total field strength of ≥ 1 V/m peak envelope power (PEP) at radar antenna 200 m away
High suppression of intermodulation products and spurious emissions in radar band to < –130 dBm/MHz through decoupled, low-intermodulation filters
Flexible setup at 100 m to 300 m from radar for taking local conditions into account
Tests in normal radar operating mode
Flexible, modular system based on standardized instruments; expandable for other interference tests

Brief Description

The R&S^®TS6650 detects potential interference to air traffic control (ATC) radar systems caused by LTE and WiMAX^™ emissions in the adjacent frequency band. The effectiveness of counteraction is verified on the radar.
