A new Noise Figure analysis mode is available for the Spike spectrum analyzer software. Noise Figure analysis is one of the most useful metrics for RF test engineers, characterizing the noise contributions of an electrical system, as well as the individual electrical components within the system. Spike is Signal Hound’s spectrum analyzer software, compatible with […]
Test and Measurement Tips
Kit verifies isolation effectiveness of RF shielded enclosures
The JRE TVK Isolation Tester can help verify the proper shielding isolation of RF enclosure test set-ups. This test combination, consisting of the STA-1, a sensitive handheld spectrum analyzer, and the HPSS-1, a high power 2.45-GHz test signal source, can easily and quickly measure enclosure isolation down to less than -100 dB. The TVK Isolation […]
Source measurement units reliably gauge currents from nanoamps to amps in a single sweep
The R&S NGU series of high-precision SMUs feature innovative current feedback amplifier technology that provides both maximum sensitivity and accuracy to reliably measure currents from nanoamps to amps in a single sweep. To handle rapidly changing load conditions typical of battery-powered communications devices switching between sleep and transmit modes, the R&S NGU features an optimized control loop […]
Economical force tester handles basic static, multistage, cyclic testing chores
Accuracy, repeatability, and documentation of results are important factors when applications and raw materials undergo force testing. The ideal test machine used for carrying out the force testing should be simple to operate and test results should be easy to read and export for further analysis. The digital Chatillon CS2 Series of force testers meets […]
Measuring and specifying microphones
One aspect of the work-at-home/stay-at-home environment of the past year has been an increased emphasis on podcasts, online meetings, and online video events. That’s why there’s more interest in microphone technology among those interested in producing a higher-quality experience. Here’s a short run-down on microphones and how they are typically measured and quantified. A microphone […]
Trigger-and-decode scope setup handles 1000BASE-T1 automotive Ethernet
The new K58 option for R&S RTO and R&S RTP scopes is billed as the world’s first triggering and decoding solution for 1000BASE-T1. The flexibility of Automotive Ethernet makes the simple twisted-pair network technology a candidate for an ever-increasing range of in-vehicle networks. To verify, commission and troubleshoot designs based on an Automotive Ethernet communication […]
Thanks, Pythagoras, for the basic science behind the theodolite
Pythagoras was a larger than life pre-Socratic philosopher, born on the island of Samos. The Pythagorean Theorem relates the lengths of the three sides of a right triangle. Undoubtedly the most familiar theorem in mathematics, it had been known previously in Mesopotamian, Indian and Chinese cultures, but it was elaborated, made part of the over-all […]
Waveguide-to-coax adapters use European IEC standard flanges
A new line of euro-style flange, waveguide-to-coax adapters are candidates for radar, satellite and wireless communications, and test instrumentation applications. Fairview Microwave’s new waveguide-to-coax adapters cover a wide range of waveguide sizes that include European IEC standard flanges (including UBR square cover, UDR and PDR types), WR-22 to WR-430, right-angle and end-launch coaxial connector options, […]
IEEE 802.3ch multi-gigabit Ethernet compliance setup covers PMA transmitter tests
The TekExpress Multi-Gigabit Automotive Ethernet Compliance Test Solution is billed as the first-in-market solution to meet the requirements of complex automotive designs. As newer automotive technologies such as autonomous driving, 5G and connected car solutions develop, the paths carrying the vast amount of data necessary to support those technologies must be tested to ensure reliable […]
Antennas and antenna measurements
Most antenna designs operate via the resonance principle, which is based on the fact that electrons moving through a conductor reflect back toward the power source when encountering a discontinuity. When current, caused by a radio signal’s induced voltage, reaches the end of the antenna element, it is reflected, travels in the reverse direction, and […]
