The Saker-MV ISOVP Probe enables high-voltage isolated measurements via fiber optic cables. Optical fiber isolation provides high-voltage safety and increased signal integrity due to absence of induced interference from external fields. This also allows for much higher common mode rejection as compared to conventional differential probes. The probe head can be remotely put in standby, […]

Test system handles latest Wi-Fi 6E devices
A newly integrated testing system allows testing to the new IEEE 802.11ax WLAN standard. The new band adds to the already available 2.4 GHz and 5 GHz bands. Anritsu’s Wireless Connectivity Test Set MT8862A has been integrated with the EMITE E600 Reverberation Chamber, allowing developers to test the OTA TRP/TIS performance of IEEE 802.11ax devices […]
Test setup handles high-speed Ethernet cable assemblies up to IEEE 802.3ck
New compliance test automation software from Rohde & Schwarz for IEEE 802.3 cable assemblies allows for precise and time-saving compliance tests of high-speed cables and backplanes according to the IEEE 802.3bj, by, cd and ck standards. The R&S ZNrun vector network analyzer automation suite controls a vector network analyzer and a switching solution from Rohde […]
What is Fourier transform IR spectroscopy?
Most EEs probably think of a Fourier transform in terms of an operation that converts time-based waveforms on a scope into their component frequencies. But Fourier transforms also play a role in infrared spectroscopy. It might be easiest to explain Fourier transform infrared spectroscopy by contrasting it with conventional spectroscopy. Also called “dispersive spectroscopy,” the […]
Ohm meter features low stimulus voltage for sensitive components
The AltoNovus OR-01 OhmRanger-LCV Low Compliance Voltage Ohmmeter is an accurate, affordable, portable meter which can measure a wide range of resistances simply and quickly. Individually factory-calibrated, this meter measures resistances from greater than 100 MΩ down to 10 Ω. Additional built-in features include a signal-to-noise measurement, which indicates how much noise, variation, and ac […]
High-performance LCR meter spans 4 Hz to 10 MHz range
The R&S LCX family of LCR meters serves all established impedance measurements plus specialized measurements for selected component types and provides both, the high accuracy required in R&D, and the high speed needed in production test and quality assurance. With its supported frequency range from 4 Hz to 10 MHz, the R&S LCX is suitable […]
The difference between VSWR and the S11 reflection coefficient
A traveling signal along an electrical transmission line reflects back toward the source when one or more events occurs: One or both of the conductors is open at the far end (receiving end). The conductors are shorted at the far end (very common). There is a discontinuity in the characteristic impedance or an electrical fault […]
Wireless system supports Wi-Fi 6, 6E OTA tests
ETS-Lindgren’s EMQuest software now supports the most current versions of Wi-Fi while maintaining backward compatibility.
Digitizer cards stream data over PCIe bus at 12.8 GB/sec
Two new PCIe Digitizer cards from Spectrum Instrumentation bring next-generation performance to PC-based instrumentation. Using 16-lane, Gen 3, PCIe technology, the cards are capable of streaming acquired data over the bus at a staggering 12.8 GB/sec. That is nearly twice as fast as any other PCIe Digitizer currently on the market. Furthermore, it allows the […]
