The GWInstek C-1200 LoRa Tester is a one-box tester that incorporates a multitude of LoRa transmit and receive tests. The C-1200 provides transmitter tests that include spectrum analysis, time domain, FEI (Frequency Error Indicator), and TOA (Time-On-Air). LoRa Receiver tests include sensitivity, BER (Bit Error Rate), and PER (Packet Error Rate). In addition to sub-gigahertz […]
Testing regimes for the new frequencies and features of 5G
Measurements taking place in pre-commercial 5G network trials provide new insights and overcome uncertainties before the technology’s formal launch. By Rohde&Schwarz The 3rd Generation Partnership Project (3GPP) defined fifth-generation (5G) cellular technology in Release 15, which updated mission-critical (MC) communications and MC service functions, to meet the International Telecommunication Union’s IMT-2020 performance requirements. IMT-2020 laid […]
The complexity of wireless receiver testing
Eric Hsu | Keysight Technologies, Inc. The demand for wireless communications now challenges the physical limitations of today’s wireless communications systems. Interference can easily arise when systems operate in a crowded wireless environment using a shared spectrum. Signal congestion makes the process of designing, testing, and isolating system problems more complex. In the next few […]

The RF Drive Test System Incorporates a ThinkRF R5750 Real-Time Spectrum Analyzer with GNSS (plus optional D4000 RF downconverter/tuner for performance up to 40 GHz), CelPlan […]
Waveguide shorts and shims cover 1.72 GHz to 110 GHz
A new family of waveguide shorts and shims consists of 36 models with waveguide sizes from WR-430 to WR-10 and operating frequencies from 1.72 GHz to 110 GHz in 18 waveguide bands. This new line provides superior RF performance and is ideal for use in satellite communication, radar, wireless communication, and RF test and instrumentation […]
Test bench checks out automotive radomes
Löhnert Elektronik is integrating the R&S QAR imaging tester from Rohde & Schwarz into its new end-of-line test benches for automotive radomes. Now the test benches can reproducibly test the reflection and transmission of these sensor covers over their entire surface at cycle rates of less than ten seconds. Löhnert Elektronik, a specialist in custom […]
Instrument runs true PIM analysis over fiber for IQ data
The IQ Fiber Master MT2780A multi-port CPRI-based RF and PIM (passive intermodulation) analyzer that is the first instrument to perform true PIM analysis over fiber and present RF spectrum results derived from IQ data. The MT2780A reduces test costs and time by providing field engineers, field technicians, and third-party contractors with a single instrument to […]
New time-saving functions for ESW EMI test receiver
Rohde & Schwarz has integrated the fast time-domain scan as standard in its R&S ESW EMI test receiver. It works with double bandwidth to increase measuring speed. Also new is the R&S EWS-K58 multi CISPR ADP option. It precisely shows the effects of interference on digital communication systems. The option accelerates CISPR 11 tests on […]
Instrumentation supports wake-up signal test in NB-IoT devices
New radio communication testers have implemented the many new NB-IoT features introduced with 3GPP Releases 14 and 15. The R&S CMW500 and R&S CMW290 both introduced wake-up signal support, among other Release 15 features, with the most recent firmware releases. For NB-IoT long-term monitoring applications, this wake-up signal can be leveraged to enable either far […]
