In general, the electrical characteristics of circuits associated with high-frequency instruments vary significantly with time. Signal sources, receivers, and interconnections drift with vibrations, cable flexing, temperature, humidity, and so forth. That’s why vector network analyzers (VNAs) are only treated as being time-invariant over short time periods (a few hours). Thus a VNA must be calibrated […]

DIO card completes PCIe instrument family
Spectrum instrumentation’s family of PCIe instrument cards also includes digitizers and waveform generators. Automated test systems often need to generate and measure analog signals. They often need to provide digital I/O for status monitoring and control of test hardware or industrial process equipment. With the addition of the M2p.7515-x4 digital I/O card, Spectrum Instrumentation completes […]
Instrument monitors optical fiber Bragg grating sensors in static and dynamic apps
A new optical interrogator, the MXFS, provides stability against external influences and a high-sensor capacity of 128 channels per device, making it a candidate for use among engineers carrying out measurements within unpredictable environments, such as construction sites or laboratories. MXFS is a fibre Bragg grating measurement device, based on the BraggMETER technology, that is […]
Raspberry Pi for DAQ
Though they are more closely associated with the maker space, Raspberry Pi boards can be effective at handling stringent industrial measurements. Steve Radecky, Measurement Computing Corp. Originally designed to be a cheap, almost disposable computer, Raspberry Pi was created to get kids interested in programming. Since its introduction in 2012, Raspberry Pi has become the […]

Delivering laboratory-level accuracy in a battery-powered dc calibrator, the 2000 Series is a cost-effective calibration/simulation tool which is a candidate for applications spanning the consumer, medical, automotive, process control and many other industries. The […]
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 […]
Microphone power modules target sound pressure level measurements
The GRAS 12BA and 12BB Microphone Power Modules areaimed at engineers who need to power CCP measurement microphones and would like seamless integration of microphone sensitivity data via TEDS. These single-channel (12BA) and four-channel (12BB) USB-powered modules provide integrated TEDS support and are competitively priced for production test applications, saving time during setup and configuration. […]
NI CEO: COVID-19 on day one
NI CEO Eric Starkloff’s first decision was what to do about COVID-19 the night before he took over on February 1, 2020. Since then, he’s seen the opportunities in communications resulting from the pandemic. How would you like to take on a new leadership role just as a pandemic takes hold? That’s what Eric Starkloff […]
Data streaming/visualization platform works with logging, 6.5-digit DMMs
A native integration mates the Keithley DAQ6510 and DMM6500 instruments with Initial State, an loT dashboard for data streaming and visualization for world-class, remote data access. Keithley and Initial State, both Tektronix companies, collaborated to integrate Initial State’s data streaming and visualization platform with the Keithley graphical DAQ6510 and DMM6500. This integration gives a DAQ6510/DMM6500 […]
Fixed-load VNA kits support up to 50 GHz calibration capability
A new series of short-open-load-through (SOLT) calibration kits are designed for use in lab, test and measurement, and RF and Microwave production test applications. Fairview’s expansion of its VNA calibration kit line consists of 12 models including short circuit, open circuit and load kits (SOL), as well as short circuit, open circuit, load and […]
