A bad transistor can sometimes be detected by its partly burned or distorted appearance, but more often there is no visible indication. One approach to troubleshooting is to substitute a known good component, but that is a costly way to go. Also, it is not reliable because an outside defective component can instantly destroy the […]
Test gear speeds development of CAT M1 and NB IoT modules
Virtual drive tests during the development phase of CAT M1 and NB IoT modules help find and fix problems at an earlier stage. New test setups also enable seamless cellular coverage and reliable connectivity before the integration process continues and further field tests are performed. Network-specific integration tests and field tests include analysis of unique […]
AWGs deliver 24-output swings on up to eight channels
Four new models of the generatorNETBOX family have output swings of up to 24 V on up to eight channels to cover demanding test applications. The new units use the latest 16-bit digital-analog-converters and offer two different speed ranges: The DN2.657 models output waveforms at rates up to 125 MS/sec while the DN2.654 units have […]
IEEE 802.11ax compliant WLAN signaling test setup handles SISO, MIMO, OFDMA modes
An IEEE 802.11ax test solution for WLAN access points in multi-user operation (OFDMA) employs an R&S CMW270 Wireless Connectivity Tester to test the RF characteristics of receivers and transmitters and to determine the data throughput in the transmit and receive directions. With an R&S CMW270 Wireless Connectivity Tester and the WLAN 11ax signaling test option, […]
Class AB high-power amplifiers offer optional heatsinks
A new series of high power, Class AB broadband amplifier modules incorporate GaN, LDMOS or VDMOS semiconductor technology. The combination of high linearity and efficiency with low distortion over a wide dynamic range makes them candidates for a variety of applications including communications systems, military radio, radar, signal jamming, test and measurement and base stations. […]
Economical RF signal sources support R&D, test & services apps
The AIM-TTi TGR2051 and TGR2053 RF Signal Generators are a major revision of the successful TGR 2000 series, which both offer exceptional performance, low phase noise, and offer output signals from 150 kHz to 1.5 and 3 GHz respectively. These versatile RF generators provide excellent frequency accuracy and stability, large signal amplitude range, low phase […]
Automated testing for automotive ethernet gear
The new Automotive Ethernet Tester (AET) is a highly-automated test system for OPEN ALLIANCE TC8 switching and AVB/TSN tests at the component level. The Automotive Ethernet Tester consists of a 19-in. test rack with control and analysis software. A PC control unit regulates the test system. Depending on the implementation, the test platform can contain […]
Will 5G make earth-bound radio telescopes impractical?
Though 5G is a promising technology, astronomers and Earth scientists are worried that 5G frequencies could interfere with the scientific use of previously quiet parts of the electromagnetic spectrum. The Federal Communications Commission recently came out with rules allowing experimental devices to use frequency bands between 95 GHz and 3 THz. Scientists see several problems […]
Electromagnetic field analyzer measures in time and frequency domains
The Microrad NHT 3DL Electromagnetic Field Analyzer is designed to measure electromagnetic fields in both time and frequency domains and in compliance with all the main international standards and regulations. A wide selection of interchangeable electromagnetic field probes allows this handheld analyzer to measure complex electric and magnetic fields from dc to 1 MHz in […]
