TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • Ensuring Test Site Compliance for Radiated Emissions With Normalized Site Attenuation

    This application note provides a synopsis of Normalized Site Attenuation (NSA) and Reference Site Method measurements which indicate a challenging but important aspect of radiated emissions measurements on an OATS, SAC, or FAR.  

  • An Introduction To Direction Finding Methodologies

    All direction finding methodologies are meant to determine the physical or geographical location of a source of radio frequency energy. The choice of an appropriate direction finding methodology to use for a given application is largely a function of the target signal's characteristics, such as frequency and modulation, but is also influenced by the propagation environment as well as cost and complexity.  Recent advances in the development of hybrid direction finding methodologies attempt to overcome some of these restrictions and increase accuracy by using a combination of methodologies.

  • Introduction To RNVNA, A Multiport Network Analysis Solution

    In many RF applications it is necessary to make multiport measurements. The RNVNA, a multiport network analysis solution, links up to 16 1-Port analyzers together into a multiport network analysis system. Each of the 16 analyzers will make individual vector reflection measurements and scalar transmission measurements from port to port.

  • Testing For Coexistence In Crowded And Contested RF Environments

    In this paper, we review some of the key research, development, test and evaluation (RDT&E) challenges that arise when developing and deploying systems that need to operate in congested and/or contested RF environments.

  • How To Test USB Power Delivery Over Type-C

    USB Type-C compliance test standards are more complex due to higher data transmission speeds and more power. Successful testing requires accurate and compliant test instruments, software, and fixtures.

TEST & MEASUREMENT SOLUTIONS

The dB-3907 TWT Amplifier (TWTA) is designed to use two wideband, periodic permanent magnet (PPM)-focused TWTs to amplify CW, AM, FM or pulse-modulated signals. The dB-3907 offers higher saturated output power and improved harmonic performance when compared to a single TWT approach.

The Si4133G Dual-Band RF synthesizer is a fast settling integer-N synthesizer

Qorvo offers the 1800 W, 65 V, 1.0 – 1.1 GHz QPD1025L as the highest GaN transistor on the market. This discrete GaN on SiC HEMT has a package that features input pre-match resulting in ease of external board match and saved board space.

Radar simulation systems (i.e., RF sources and/or receivers) must perform to an exacting minimum standard if they are to accurately prove the field worthiness of EW systems.

Pentek offers the Talon® RTX 2684 as a 26 GHz sentinel intelligent signal scanner recording system. The system provides SIGINT engineers the ability to scan the RF spectrum from 1 GHz to 26 GHz for signals of interest and monitor or record bandwidths up to 500 MHz wide.

Model HP 4268A is a capacitance meter designed for testing high value multilayer ceramic capacitor (MLCC) designs

The dB-9002 from dB Control is a custom-mounted Dual Instantaneous Frequency Measurement (DIFM) unit designed to operate in the C, X, and Ku-band frequency range and provide highly accurate measurements at 100 ns to CW pulse width measurements.

The dB-3908 TWT Amplifier (TWTA) is designed to use two wideband, periodic permanent magnet (PPM)-focused TWTs to amplify CW, AM, FM or pulse-modulated signals. The dB-3908 offers higher saturated output power and improved harmonic performance when compared to a single TWT approach.
