TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • Directivity And VSWR Measurements: Understanding Return Loss Measurements

    The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately no directional device is perfect, leading to potentially dramatic measurement errors. In this note we show that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power.

  • How To Analyze Passive Low Frequency Components With A Rohde & Schwarz Oscilloscope

    This white paper presents a technique for easily and quickly analyzing low frequency response on an oscilloscope with the R&S®RTx-K36 frequency response analysis (Bode plot) option, which uses the oscilloscope’s built-in waveform generator to create stimulus signals ranging from 10 Hz to 25 MHz.

  • Accurately Measure Your UWB Device's Time Of Flight

    The R&S®CMP200 radio communication tester together with the R&S®CM-Z300A time of flight kit provides an accurate setup for time of flight measurements – in validation, calibration and certification.

  • Field Probe Correction Factors

    To better achieve accurate field level measurements, it is helpful to have an understanding of field probe calibrations, the factors generated, and what’s presented as data during testing. This application note presents how to utilize the factors presented for inclusion into test data, how to generate composite measurements, and why calibrations are performed at selected frequencies.

  • 5G New Radio Over-The-Air Base Station Receiver Tests

    This application note describes all mandatory RF receiver tests, according to the Release 16 (V16.3.0). It also offers a brief introduction about the different R&S OA antenna test solutions and how they are applicable for base station conformance testing.

TEST & MEASUREMENT SOLUTIONS

D-TA Systems offers the MFEL 1000 portable ELINT data collection solution designed to provide automatic spectrum scanning for signal activity (pulse or CW), PDW extraction and de-interleaving to tracks where signal characterization is performed automatically. The system includes a built-in 6 TB (expandable to 18 TB) SSD data storage for I/Q data collection in both on-site and off-site analysis.

The dB-9003 and dB-9005 from dB Control are custom-mounted Integrated Stabilized RF Sources (ISRFS) designed to operate in the I and Ka-band frequency range. Both products feature high accuracy and a wide temperature operating range. They can be controlled and set up with a digital port. The units are packaged in a custom configuration with conduction cooling.

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 GORE® PHASEFLEX® Series offers the smallest, lightest, internally ruggedized microwave/RF test assemblies for high density interconnection in RF and uW modular applications as well as in high speed digital testing. These assemblies feature ON cable construction and provide consistent, repeatable measurements with electrical performance up to 18, 26.5, 40, or 50 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.

Pentek offers the Talon® RTX 2684 as a 26 GHz sentinel intelligent signal scanner recording system. The system provides SIGINT engineers the ability to scan the RF spectrum from 1 GHz to 26 GHz for signals of interest and monitor or record bandwidths up to 500 MHz wide.

The Si4133G Dual-Band RF synthesizer is a fast settling integer-N synthesizer

Radar simulation systems (i.e., RF sources and/or receivers) must perform to an exacting minimum standard if they are to accurately prove the field worthiness of EW systems.
