TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • The Journey Of A Signal: Optimize Your Signal Analysis Measurements

    What happens to the signal of your device once it enters the signal analyzer? This white paper walks through the high-level design of a signal analyzer and how this knowledge can be used to avoid mistakes and make optimum measurements.

  • Performing Differential Noise Figure Measurements

    In recent years, numerous improvements have been made in noise figure measurements through better algorithmic understanding of the measurements, more sensitive receivers, and less error-prone methods of processing noise power measurements. Anritsu has incorporated a number of these improvements in the single-ended Noise Figure Measurement Option of the VectorStar vector network analyzer (VNA) platform. This application note offers insights into and examples of performing differential noise figure measurements.

  • 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.

  • Breakdown And Leakage Current Measurements On High Voltage Semiconductor Device

    Coupling a Keithley SourceMeter SMU instrument like the 2470, KickStart software, and their associated accessories meets all test needs and further facilitates research of high voltage materials and semiconductor devices.

  • Telecommunications Testing Using AR Amplifiers

    This application note explores a number of testing requirements for telecommunication devices and how to benefit from AR RF/Microwave Instrumentation’s products. The paper will cover two broad categories of device testing – characterization and reliability – within mid to high power systems.

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. 

As its model number implies, the 745T-20C is a digital delay generator with 20 channels in one unit. It features a 100 ps time resolution (standard, with an optional 250 fs time resolution), 5 ps jitter (internal trigger), a 25 ps jitter (external trigger), 1 ns output rise times, and more.

Dow-Key Microwave offers a CANbus-based Coaxial Switch Matrix system with Ethernet, GPIB, RS-232, RS-485, and CANbus control interfaces. This matrix performs up to 18 GHz and can be configured with up to four SP10T switch assemblies

The R&S FSW85 is the latest addition to Rohde & Schwarz’ family of signal and spectrum analyzers. It is the only device on the market designed to cover the frequency range from 2 Hz to 85 GHz in a single sweep, allowing users to test baseband and RF with a single analyzer. Test setups are now much simpler, since the R&S FSW85 does not require harmonic mixers. An internal preselection feature suppresses the image frequency and other spurious emissions that commonly occur during harmonic mixing.

Rigol offers the RSA5000 Series Real-Time Spectrum Analyzer delivering class leading 7.45 µsec 100% probability of intercept, meaning that any pulse with duration greater than 7.45 µsec will be captured and accurately displayed.  This device includes advanced trigger capabilities, making the task of identifying and isolating signals of interest easier.
