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 […]
Network installation and maintenance test tool adds 400G module
A 400G module for the OneAdvisor 800 network installation tool provides advanced 400G transport test and maintenance functionality for business service and network core technicians working in the field. Combining its transmission protocol and fiber network modularity, the OneAdvisor 800 offers unprecedented testing performance for technicians who must carry their gear into the field. Building […]
Electric charge and instruments used to measure it
Many devices have been built for measuring electric charge. One of the first was the gold-leaf electroscope. When a charged object touches the metal knob at the outer end of the rod, the charge flows down to the leaves. The leaves diverge due to the repulsion of like charges they have received. The degree of […]
Dual-independent-channel AWGs feature up to 1 GHz bandwidth, 5 Gsa/sec sampling
Siglent’s SDG7000A series of dual-independent-channel arbitrary waveform generators feature up to 1 GHz bandwidth, 5 Gsa/sec sampling, 14-bit vertical resolution, and a memory depth of 512 Mpts. Arbitrary waveforms are generated with sample rates from 0.01 Sa/sec to 2.5 GSa/sec, and vector signals at 500 MSa/sec. A wide variety of test signals can be generated, […]
Copper, fiber, PoE, Wi-Fi cable tester fits in a pocket
The LinkXpert cable testers include the LinkXpert TP (Twisted Pair) model for copper wires, as well as the LinkXpert M3 model for three media types: copper, fiber and Wi-Fi. LinkXpert cable testers offer game-changing convenience for end users, packing three media types — copper, fiber and Wi-Fi — into a single device roughly the size […]
Multiport USB hub sports transfer speeds up to 40 Gbits/sec, charges/syncs up to 10 USB 3.2 devices
The Cambrionix ThunderSync3-C10 Charge/Sync Hub is a Thunderbolt-certified hub which features 10 x USB Type-C connectors and offers 3-A (15 W) charging and USB 3.2 Gen 1 data for each connected device. It is claimed by Cambrionix to be the fastest Thunderbolt to USB Hub commercially available, with the ability to control and monitor each […]
RF test system handles Bluetooth Basic Rate, Extended Data Rate, LE technologies
The FRVS RF test system has been approved by the Bluetooth Special Interest Group (Bluetooth SIG), the governing body for Bluetooth technology, for testing Bluetooth Basic Rate (BR), Extended Data Rate (EDR) and Low Energy (LE) technologies. It is estimated by ABI Research and the Bluetooth SIG that about 4.5 billion Bluetooth enabled devices were […]
