Six Axes of Calibration

In a system or on a lab bench, proper instrument calibration reduces the chances of false test results. Not all calibrations are equal, and six key factors affect quality, usefulness and cost. In Six Axes of Calibration, we highlight the importance and value of each factor. Download application note.

Frequency Synthesizer

The THOR-16000-XA multi-output frequency synthesizer from EM Research, Reno, NV, features a single 800-MHz and dual 16-GHz RF outputs. The unit locks to an external 50-MHz reference and exhibits low phase noise at both RF output frequencies. At 100-KHz offset, phase noise is ≤118 dBc/Hz @ 800 MHz and ≤94 dBc/Hz @ 16...

Standing Still May Improve Antennas That Scan in All Directions

Antennas often need to trace circles in the sky. For example, radar arrays atop air-traffic control towers rotate to sweep signals in all directions. But spinning large objects nonstop takes a lot of time and mechanical energy. So scanning from a stationary position could speed up...

New MRI Technology Eliminates Longtime Limits

A new technology harnesses imperfections that typically compromise MRI exams to create images resolved enough to enable consistent diagnoses across populations for the first time. Traditional MRI radio waves “light up” some parts of a sample better than others, with imperfections blacking out...

V-FASTR Radio Transient Classifier

The V-FASTR (VLBA Fast Transient Experiment) system was motivated by the desire to monitor the radio sky for interesting transient events. To be confident that no interesting extragalactic event is missed, every VFASTR candidate requires human review and evaluation. Candidates consist of pulsar pulses, spurious...
