How to protect sensitive RF instrumentation
May 5, 2022
Spectrum and vector network analyzers like the SIGLENT SSA, SVA, and SNA series products feature very sensitive circuitry that can be easily damaged by electrostatic discharge or ESD. In many cases, ESD events aren’t obvious. It isn’t always a visible/noticeable event like the “wool sock shock” you may have tried as a child. ESD events … Continued
Common Fuse Information
February 9, 2022
Fuses are a common circuit element and are key to protecting from overvoltage and overcurrent situations that can damage important circuits. Fuse markings are typically stamped symbols located on the metal cap of the fuse. Here is a helpful guide to common fuse markings used with instrumentation, taking a common fuse type as an example: … Continued
