TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • RF Test Setup For Measuring Power & Harmonics

    Power measurement is accomplished by using a high-power calibrated coupler or attenuator, which gets attached to the Amplifier RF output connector. Harmonics are recorded similarly by increasing the input drive from the signal source. 

  • 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.

  • 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.

  • Characterization Of An Amplifier With The Combination Of Network And Spectrum Analysis

    The general characterization of complex DUTs such as amplifiers requires the measurement of several parameters. Thanks to its versatility, the R&S® ZNL is an economic solution that can characterize a variety of DUTs both via network analysis and spectrum analysis.

  • Verifying The Clock Source

    In order to select or develop a clock generator to use in your design or to ensure that the supplied system clock has the proper performance, you'll need to consider phase noise, jitter, wideband noise and spurs as performance indicators.

TEST & MEASUREMENT SOLUTIONS

The 50S-2133 SMA from JFW is a solid-state, self-terminating 1P8T RF switch designed for economical automated RF testing applications in the 20 – 5,000 MHz frequency range.

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.

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

The EVO-RSA-6070A is part of the EVO Series of extended frequency spectrum analyzers from Avcom designed for higher performance and agility in applications with continuously changing requirements. The included SDR-style technology analyzer includes a wide bandwidth receiver and employs FPGA, DSP, and high-performance processors.

The RFvision-3 is a tunable ultra-wideband spectrum processing solution designed for 1 GHz bandwidth RF spectrum recording with advanced pulse processing. This rack-mount (3U) system is based on the DTA-9590W ultra-wideband tuner and DTA-5000 RAID server with 24 TB SSDs. It operates from 500 MHz to 18 GHz (expandable up to 40 GHz) and features 100 MHz instantaneous bandwidth.

Pentek offers the Quartz® Model 6003 high-performance Quartz eXpress Module (QuartzXM) based on the Xilinx Zynq UltraScale+ RFSoC FPGA. The RFSoC FPGA integrates eight RF-class A/D and D/A converters into the Zynq’s multiprocessor architecture, creating a multichannel data conversion and processing solution on a single chip.

D-TA Systems offers the MFEL 1000 portable ELINT data collection solution designed to provide automatic spectrum scanning for signal activity (pulse or CW), PDW extraction and de-interleaving to tracks where signal characterization is performed automatically. The system includes a built-in 6 TB (expandable to 18 TB) SSD data storage for I/Q data collection in both on-site and off-site analysis.

Qorvo offers the CMD240C4 wideband GaAs MMIC distributed amplifier housed in a leadless 4x4 mm surface mount package. The amplifier operates from DC to 22 GHz and is ideal for radar, space, satcom, test and measurement, and electronic warfare applications.
