  • 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.  

  • Testing Passive Remote Keyless Entry Systems

    Due to recent security concerns, ultrawideband (UWB) technology is making its way into automotive key fobs. Rohde & Schwarz offers a flexible test solution for the high demands of R&D and high-throughput production environments. This application note discusses flexible solutions that cover all testing technologies and fulfill the high requirements of interference-free function testing in development and production.

  • Testing LTE Release 9 Features

    LTE – the fastest growing mobile radio standard – had its beginnings in 3GPP Release 8. Initial improvements and new features were implemented in Release 9. This Application Note describes the T&M methods for LTE Release 9 features using Rohde & Schwarz instruments.


Holzworth RF Synthesizers were developed as building blocks for our Phase Noise Analyzers. High end phase noise testers require high performing, extremely stable RF sources. Due to our own stringent development requirements, Holzworth has been able to offer compact RF synthesizers with the best bundle of all around industry leading performance parameters.

Design engineers are constantly trying to minimize space in creating smaller more efficient products.  Corry Micronics’ new Micro Spanner EMI Filter matches the smallest size chassis-mounted feedthrough the industry has ever seen.  The FT40 spanner bushing filter offers a miniature diameter of 0.071”and is the optimal form factor for designs that demand efficiency in a compact footprint.  Corry’s Micro Spanner is offered in a “C” filter configuration and provides capacitance from 10 pF to 5000 pF. 

The dB-9003 and dB-9005 from dB Control are custom-mounted Integrated Stabilized RF Sources (ISRFS) designed to operate in the I and Ka-band frequency range. Both products feature high accuracy and a wide temperature operating range. They can be controlled and set up with a digital port. The units are packaged in a custom configuration with conduction cooling.

Electrostatic discharge testing is utilized worldwide by electronics manufacturers to determine the ESD susceptibility of their devices. It is extremely difficult to estimate the exact cost of ESD loss annually, but it can safely be stated that ESD requires the development and testing of many hardware prototypes and contributes to a high number of warranty claims and loss of consumer confidence if failure occurs in the hands of the customer. Given the high cost in time and materials associated with ESD hardware testing, the ability to simulate the ESD testing process in XFdtd is extremely valuable, allowing engineers to pinpoint locations susceptible to ESD damage and optimize ESD mitigation during the concept and design stage of product development.

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.

Qorvo introduces the QPC2040 single-pole, double-throw (SPDT) switch operating within the 8 – 12 GHz frequency range for commercial and military radar, communications, electronic warfare, test instrumentation, and other general purpose applications. The switch typically supports 10 W input power handling at control voltages of 0/−2 V for both CW and pulsed RF operations.

This series of ultra-low noise signal sources features exceptionally low phase noise, supplementary output at oscillator frequency, and a wide range of output frequencies and multiplication ratios. They provide a range of high-performance building blocks between 200 MHz and 3 GHz.

This series is the latest edition to Anritsu’s Spectrum MasterTM handheld spectrum analyzers. These analyzers provide the same performance as a benchtop model, but come in a portable and handheld package.
