  • Multi-Tone Testing, Theory And Practice

    Multi-tone testing was initially implemented to increase the speed of immunity testing, but it also improves equipment efficiency, offers higher flexibility, and is fully compliant to standards. Multi-tones are used in measuring modern audio levels in audio devices, broadband devices, and in internet audio.

  • Millimeter-wave Intermodulation Distortion (IMD) Measurements

    This application note discusses the complications encountered in IMD measurements (set up complexity and hardware availability being the two main issues), and how Anritsu’s ME7838A family of broadband vector network analyzers (VNAs) can be used to make millimeter-wave measurements easier and more streamlined.

  • An Introduction To Practical Real-Time Spectrum Analysis

    This application note provides an introduction to the practical uses of RTSAs to reveal important information about the performance of RF/microwave components, track down sources of interference, and monitor the spectrum for activity and security threats.

  • Programming EMI Test Receivers This application note discusses several basic methods for reading and displaying measurement results from EMI test receivers.
  • What To Look For When Choosing An Oscilloscope

    Choosing a new oscilloscope can be daunting — there are hundreds of different models to choose from with widely varying costs and specifications. This article guides you through the maze of considerations and will hopefully help you avoid making what could prove to be an expensive mistake.


ATE Systems’ Z1011A InCal Calibration Module is an in-line network calibration instrument that is designed to be able to calibrate products at any time, with or without a connected device under test (DUT), and without any user intervention or having to make changes to the hardware configuration.

The series of GORE® VNA microwave/RF test assemblies from W.L. Gore are designed to provide the most precise VNA measurements in laboratory conditions, setting the standard for vector network analyzers (VNAs) through 70 GHz. These test assemblies deliver the highest accuracy and greatest time intervals between recalibrations for many applications, including those with vector network analyzers, critical measurements, and laboratory testing.

The 8400 Series Mini-Power Meter is an inexpensive, portable and battery operated power measurement system. Consisting of the model 8441 power meter, the model 8440-01 extension cable and one or more of the 842X series of power mounts, this system allows accurate measurements at frequencies up to 26.5 GHz...
Dow-Key Microwave, a leader in the design and manufacture of switching products, acquired its Matrix line in 1999. Since that time, the line has expanded to include both standard and custom matrices supporting the aerospace, military and communication industries for both signal routing and ATE applications.

Two standard product series covering 2 to 24 GHz.

Qorvo offers the CMD240C4 wideband GaAs MMIC distributed amplifier housed in a leadless 4x4 mm surface mount package. The amplifier operates from DC to 22 GHz and is ideal for radar, space, satcom, test and measurement, and electronic warfare applications.

Rohde & Schwarz’s DDF5GTS is a high speed direction finder with outstanding realtime bandwidth (80 MHz), DF scan speed, DF accuracy, sensitivity, and reflection immunity. Its bandwidth and the utilization of three coherent receive channels not only allow for the high speed monitoring of wide frequency ranges, but also a high probability of intercept for bearings of short bursts and fast and elusive transmitters operating at unknown frequencies.

This programmable signal source is completely self-contained with an internal TCXO reference
