Evolution of LTE UE categories and how to test UEs

Learn more about the evolution of LTE UE categories and how to verify UE performance based on its corresponding category with the R&S®CMW500 wideband radio communication tester from Rohde & Schwarz. Achievable data rates in LTE mainly depend on the bandwidth, modulation scheme, MIMO support and additional features such as carrier aggregation. 3GPP Release 8 to 12 specify categories to define the supported

Signal generation for fixed-satellite applications and inter-satellite links

Fixed-satellite applications space-to-earth and earth-to-space links in the frequency range between 37.5 GHz and 51.4 GHz are used in the Q/V-band. In addition inter-satellite links make use of frequencies up to 66 GHz with a bandwidth of up to 2 GHz which are supported by the R&S®SMW200A. This makes the new 67 GHz frequency option for the R&S®SMW200A ideal for satellite applications. Fixed-satellite

Demystifying 5G – Phase noise of clock and LO components in 5G base stations

The video demonstrates a clock generator and an RF synthesizer from IDT and shows the measurement of the phase noise, contributed by these components. Massive MIMO and beamforming in 5G base stations impose stringent requirements on ADC and DAC sampling clocks and the LO signals in 5G base stations. The video demonstrates a clock generator and an RF synthesizer from IDT and shows the measurement of

High-volume multi-DUT production testing presented at GSMA MWC 2016

Rohde & Schwarz presented the R&S®CMW100 multi-device communications manufacturing test set at the GSMA Mobile World Congress 2016 in Barcelona. The multiport frontend is cutting test times to a minimum, supporting parallel receiver test function based on a broadcasting function. A small form factor puts the instrument as close as possible to the test fixture, allowing for the shortest possible cable

R&S®AVQA - RSSI monitor

The RSSI monitor in R&S®AVQA provides a great opportunity for long-term signal and noise monitoring of the radio infrastructure. Using the flags in the ED-137 voice stream, R&S®AVQA non-intrusively analyzes the RSSI level. Based on the squelch information, R&S®AVQA automatically differs between the signal and noise and reports this accordingly. The RSSI monitor in R&S®AVQA provides a great opportunity

Simulating moving emitters

Simulating moving radar emitters is important in most test cases. Simulating moving radar emitters is important in most test cases. RF variations at the input of the radar warning receiver due to approaching or outbound emitters is one factor that must be taken into account. By testing equipment in realistic tests during the development phase, engineers can optimize the equipment long before final
