  • True Differential Measurements- Characterization of Balanced Devices
    True Differential Measurements- Characterization of Balanced Devices

    Differential devices offer advantages like noise immunity, low crosstalk, high integration density, and reduced power consumption. However, they also require special measurement capabilities. There are essentially two different measurement methods available: virtual measurements, and true differential measurements.

  • Using the R&S FSW for Efficient Measurements on Multi- Standard Radio Base Stations

    This application notes introduces the Multi-Standard Radio Analyzer function of the R&S FSW and shows how it performs the measurement on multi-standard radio transmitters. It reveals interactions caused by the coexistence of signals of different cellular standards and localizes the root cause. With an example of a base station signal consisting of three radio access technologies (GSM/WCDMA/LTE FDD) it shows how easy interactions can be found. The R&S FSW is the ideal tool for trouble shooting tasks with its combination of a large bandwidth and the versatile Multi-Standard Radio Analyzer in one measurement instrument.

  • BTS System Line Sweep And PIM Testing
    BTS System Line Sweep And PIM Testing Line sweep testing is more important than ever and emerging passive intermodulation (PIM) testing requirements have lifted the bar even higher. This ultimately means the contractors, cell technicians, and performance engineers must work closely together to achieve the required quality of service. This article examines the basics of both line sweeping and PIM testing, how they work together, and why we need to perform these tests to a high standard.
  • Continuous GSM Interference From Intermodulation
    Continuous GSM Interference From Intermodulation

    This application note discusses a case in which a continuous impairment in the GSM 900 band was affecting a cell phone station’s performance, and how Narda’s IDA 2 interference and direction analyzer was able to help.

  • Flexible Radar Target Generation Using COTS Test Equipment
    Flexible Radar Target Generation Using COTS Test Equipment

    With the recent introduction of the R&S®SMW200A microwave vector signal generator, Rohde & Schwarz now offers a novel approach to flexibly and conveniently generate multiple radar target echoes for systems up to 20 GHz.  When used in combination with the R&S®FSW signal and spectrum analyzer, these commercial off-the-shelf (COTS) test instruments can be configured to support flexible radar target generation including range and target velocity emulation.

Ultralow Phase Noise Frequency Synthesizer: LTC6946 Ultralow Phase Noise Frequency Synthesizer: LTC6946
The LTC6946 is the first device in a family of high performance integer-N frequency synthesizers with integrated VCO, delivering -226dBc/Hz normalized closed-loop in-band phase noise, superior -274dBc/Hz normalized in-band 1/f noise, and best-in-class -103dBc spurious output. In a typical 900MHz application, these performance attributes help to achieve a closed-loop phase noise of -100dBc/Hz at 1kHz offset. The device is available in three frequency options: the LTC6946-1 tunes from 2.240GHz to 3.740GHz; the LTC6946-2 from 3.080GHz to 4.910GHz; and the LTC6946-3 covers 3.840GHz to 5.790GHz. In addition, each part has an on-chip output divider that is programmable from 1 through 6 to extend frequency coverage to as low as 373MHz.
