TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • Linearity Of The JFET And MOSFET When In Saturation Over The Entire Cycle

    Performing RF amplification in a way that is simultaneously linear and efficient has been a challenge in power amplifier (PA) design. Single transistor PAs can either be operated in a linear, but inefficient, current source mode of operation or as efficient, but nonlinear, switches. These techniques use two FETs, but this paper demonstrates that linear amplification can be achieved at high power with an efficiency greater than 60%, using a single FET.

  • How To Analyze Passive Low Frequency Components With A Rohde & Schwarz Oscilloscope

    This white paper presents a technique for easily and quickly analyzing low frequency response on an oscilloscope with the R&S®RTx-K36 frequency response analysis (Bode plot) option, which uses the oscilloscope’s built-in waveform generator to create stimulus signals ranging from 10 Hz to 25 MHz.

  • De-Embedding Test Fixtures For High-Speed Digital Applications

    Test fixtures are commonly used in high-speed digital measurement to connect devices to measurement equipment. Characterization and analysis in time and frequency domains help remove the influence of these fixtures.

  • Harmonic Measurement For IEC 61000-4-3 And Other Radiated Immunity Standards

    Amplifiers exhibiting significant harmonic distortion in immunity test systems can exhibit broadband characteristics that result in measurement uncertainty and unacceptable errors. This app note addresses acceptable harmonic measurement standards and other radiated immunity standards.

  • Test Automotive Radar Interference Mitigation

    Automotive radar is crucial for achieving Net Zero targets in the automobile industry, and the R&S AREG800A radar echo generator is essential for testing sensor immunity to interference.

TEST & MEASUREMENT SOLUTIONS

Holzworth’s multi-channel RF synthesizer architecture is a complete success story. These compact, 1U high, 19in rack mountable chassis can be configured with up to 8 independently tunable channels. All integrated channels are 100% phase coherent. Holzworth has designed the multi-channel platform for integration of our HSM Series Single Channel Synthesizers to maximize channel-to-channel stability via a conductively cooled, fan-less enclosure.

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 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.

The Si894x is a galvanically isolated delta-sigma modulator which outputs a digital signal proportional to the voltage level at the input. 

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 series of GORE® VNA microwave/RF test assemblies from W.L. Gore are designed to provide the most precise VNA measurements in laboratory conditions, setting the standard for vector network analyzers (VNAs) through 70 GHz. These test assemblies deliver the highest accuracy and greatest time intervals between recalibrations for many applications, including those with vector network analyzers, critical measurements, and laboratory testing.

The SMS7630 Series comprises low-cost, surface mountable, plastic packaged silicon mixer Schottky diodes designed for RF and microwave mixers and detectors. They include low barrier diodes and zero-bias detectors that combine Skyworks advanced semiconductor technology with low-cost packaging techniques. All diodes are 100 percent DC tested and deliver tight parameter distribution, which minimizes performance variability.

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.
