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 […]
Test and Measurement Tips
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 […]
Software bundle helps engineers optimize test systems
The Test Workflow subscription bundle for automating test systems expands engineers’ access to the software needed to design and automate a test or measurement system through a single software license. With engineers firmly planted at the center of digital transformation, they need to build better, higher performing products faster than ever before. To help them […]
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, […]
Can HAM signals bouncing off the ionosphere really find the Malaysian Airlines MH370 crash site?
The Australian edition of the TV show 60 Minutes recently aired a piece involving retired British Aerospace engineer Richard Godfrey who says he knows where the Malaysian Airlines Flight MH370 went down eight years ago. Godfrey told 60 Minutes he used an amateur radio technology called Weak Signal Propagation Reporter (WSPR) to track the airliner’s […]
