TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • Power Supply Control Loop Response Measurements (Bode Plot)

    The R&S® RTx-K36 frequency response analysis (Bode plot) option provides a low-cost alternative to low frequency network analyzers or dedicated standalone frequency analyzers. 

  • 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.

  • VSWR Conversion To Reflected Power

    VSWR measures how efficiently RF power is transmitted through a load, with high VSWR indicating poor efficiency. Explore VSWR's relation to return loss, reflection coefficient, and mismatch loss.

  • Directivity And VSWR Measurements: Understanding Return Loss Measurements

    The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately no directional device is perfect, leading to potentially dramatic measurement errors. In this note we show that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power.

  • Load Transient Response – Enhancing Loop Stability Testing

    Ensuring stability in power supply design requires validating switching converter stability through frequency loop and load transient responses, aided by modern oscilloscopes for visualizing PWM signals and identifying converter effects.

TEST & MEASUREMENT SOLUTIONS

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

The A.H. Systems' line of Current Probe Calibration Fixtures are a great way to keep your broadband Current Probes, and Injection Current Probes calibrated and up to date. Their rugged design ensures long life, and faultless operation over the wide calibration frequency range of 10 kHz to 1000 MHz.

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 SI893x’s 0 to 2.25 V specified input range is ideal for isolated voltage sensing. The Si8935/36/37 provides delta-sgma modulated output with flexible options for external or internally generated clock.
