    This white paper covers the different types of Anaren cased and caseless hybrid couplers, as well as their typical operating characteristics, and equations for each specification.

  2. How To Quickly Evaluate High-Performance Oscillators Using Holzworth HA7402A Phase Noise Analyzer
    12/4/2017

    The process of evaluating the performance of ultra-low-phase noise oscillators requires phase noise test systems with lower measurement times, lower noise floor capabilities, and high reliability and repeatability of test data.

  3. Noise Power Ratio Signal Generation And Measurement
    11/30/2017

    There are many noise power ratio (NPR) measurement techniques used to test high performance multi-carrier amplifiers. Rohde & Schwarz offers this application note to assist as a guide to generating NPR stimulus signals and measure the resulting NPR of a device under test. 

  4. Pulse Descriptor Word (PDW) Streaming With The R&S®SMW200A
    11/30/2017

    Radar warning receivers (RWR) and electronic support measures (ESM) require signal validation against realistic and agile radar scenarios. In the past, these complex scenarios have only been available with dedicated and highly integrated radar scenario simulators. Now, the R&S®SMW200A vector signal generator has been designed with the capabilities to take on the role. The instrument can generate the most modern I/Q modulated radar signals from streamed pulse descriptor words (PDW) received via LAN.
