Calibration

What’s all this VNA calibration stuff?

February 11, 2022 By Lee Teschler Leave a Comment

VNA calibration

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

November 8, 2021 By Martin Rowe Leave a Comment

Spectrum Instrumentation

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 […]
