Minimum pulse repetition rate frequency for EMI enabled analyzers
June 9, 2022
The EMI toolkit available for many SIGLENT spectrum analyzers, such as the SSA3X, 3X Plus, SVA, and X-R series, feature a Quasi-peak detector that was designed to CISPR-16 specifications, which include pulse repetition rates. The EMI toolkit has been tested with pulse repetition rate minimum of 20 Hz, but has not been tested below this. … Continued
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 24, 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

What is the Distance-to-Fault (DTF) function measuring?
September 16, 2021
The Distance-to-Fault function (DTF) is an optional feature for the SIGLENT SVA1000X series of spectrum/vector network analyzers and is included free with the SSA3000X-R series of real-time spectrum analyzers. It is useful for determining the physical location of breaks, dielectric degradation, and other issues in cabling, connectors, and adapters. This technique utilizes a swept signal … Continued
What is the difference between SMA and 3.5 mm RF connectors?
September 14, 2021
SMA and 3.5 mm RF connectors are very similar and should be mechanically compatible, but do have some electrical differences that may be important for your application. For best performance, use SMAs with SMAs and 3.5 mm connectors with 3.5 mm connectors. If you question the connection integrity, you can use connector gages to verify … Continued
What technique does the SVA1000X/SSA3000X-R use for the Distance-To-Fault function?
August 12, 2021
The SIGLENT SVA1000X and SSA3000X-R series of spectrum analyzers have a Distance-To-Fault feature that is useful for determining the physical location of breaks, dielectric degradation, and other issues in cabling, connectors, and adapters. This technique utilizes a swept signal source to produce an output signal that covers a known frequency range. As the impedance of … Continued
