  • Measure Group Delay Without LO Access
    Measure Group Delay Without LO Access

    In order to operate in a satisfactory matter, a mixer needs to have well controlled amplitude, phase response, and group delay. Constant group delay is especially important in wireless and satellite communications systems and in applications involving high target resolution in surveillance systems. When mixers are used to measure group delay in frequency converters, some setbacks can occur if the local oscillator isn’t accessible...

  • Introduction to Radar System and Component Tests
    Introduction to Radar System and Component Tests

    This White Paper provides a general overview of different military and commercial radar systems. It also touches some typical measurements challenges on such systems and their components.There is a complementary application note, a new version of the 1MA127 which provides information on radar test and measurement to the main target groups A&D and Automotive. Addtionally it provides an overview of core radar-related products from Rohde & Schwarz.

  • 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.

  • 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.

  • Overview Of Technologies For Millimeter-Wave OTA Measurement
    Overview Of Technologies For Millimeter-Wave OTA Measurement

    As Over The Air (OTA) measurements become more important in 5G technologies, Anritsu proposes a new measurement method for solving millimeter-wave OTA measurements that solves the current Far-Field Measurement (FFM) challenges, and helps to reduce measurement costs. Based on actual measurement results, Anritsu's Near-Field Measurement (NFM) method is capable of offering improved measurement sensitivity. Anritsu also introduces an NFM solution for the E-band using Non-Linear Transmission Line technology. This white paper discusses how Near-Field Measurement technology works, the advantages of using it, and comparisons between NFM and FFM measurement results.

Digital Delay/Pulse Generator: Model 577 Digital Delay/Pulse Generator: Model 577

Berkeley Nucleonics’ model 577 is a digital delay/pulse generator with its own trigger, its own gate, its own delay and width settings, and eight outputs – each configurable with their own pattern. It provides precise delays and widths with 250pS resolution for times up to 1000 seconds.

High-End Signal and Spectrum Analyzer: R&S FSW85 High-End Signal and Spectrum Analyzer: R&S FSW85

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.

Real-Time Spectrum Analyzer: RSA5000 Series Real-Time Spectrum Analyzer: RSA5000 Series

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.

Sensors Millimeter-Wave: Doppler & Ranging Sensors Millimeter-Wave: Doppler & Ranging

Ducommun’s line of millimeter-wave Doppler and ranging sensors are ideal for automotive radar and Doppler ranging radar applications. They features a compact size, low 1/f noise, high sensitivity, low harmonic and spurious emission, and a circular polarized waveform.
