Advanced Radar Analysis Tools For Measuring Modern Radars
In this application note, Tektronix discusses how its portfolio of test equipment reduces testing uncertainty in the design process and delivers confidence in the integrity of increasingly complex radar designs.
Application Note: Practical Tips On Measuring Interference By utilizing the ISM (Industrial-Scientific-Medical) frequency bands, the wireless industry has been able to exploit the increasing popularity of unlicensed communication systems. However, their unlicensed nature carries with it the seeds of serious signal interference problems. Such ISM system designs are type-approved but are then installed by unlicensed owners or contractors. These conditions sometimes lead to signal configurations that unintentionally interfere. The objective of this article is to present measurement tips and procedures which will help a field technician measure signal interference in operating communications systems. By Anritsu Company
The Impact Of Return Loss On Base Station Coverage In Mobile Networks
In many cases of designing and building cellular infrastructure, there are variables that the installers are and are not able to control. Important variables that are controllable are the losses in the cable feed system due to reflections and absorption. This white paper focuses on the system losses due to reflections, which can be measured using a cable and an antenna analyzer such as the Anritsu Site Master.
Doppler Generation For Moving Target Testing
Channel Environment Replicator (CER) applications simulate and recreate outdoor environments in which radar systems must operate. It’s a much less expensive testing method when compared to the potential complications encountered in more traditional field testing, though testing a moving target in such an application isn’t all that simple.
Application Note: Software-Defined Radio Testing Using Real-Time Signal Analysis
Software-defined radios are driving the integration of digital signal processing and radio frequency capabilities. This integration allows software to dynamically control communications parameters such as the frequency band used, filtering, modulation type, data rates, and frequency hopping schemes. Software radios, however, introduce a host of new problems not present in traditional wireless designs...

TEST & MEASUREMENT SOLUTIONS

Bird’s® Wideband Power Sensor Series (WPS) never requires field calibration, only requires calibration once per year and are traceable to National Institute of Standards and Technology (NIST). The WPS measures True Average Power, Peak Power, and Duty Cycle directly with exceptional accuracy and uses these precise measurements to calculate a wide range of other important factors, such as VSWR, Return Loss, Reflection Coefficient, Crest Factor, Average Burst Power, and CCDF.

Base Station Analyzer: BTS Master MT8220T

The BTS Master MT8220T is Anritsu’s third generation high-performance handheld base station analyzer that has been specifically developed to advance the support for 4G wireless networks as well as installed 2G, 3G and WiMAX networks. The MT8220T provides 20 MHz bandwidth modulation quality for LTE eNodeB testing and is equipped with a high-contrast, touch screen display and backlit key panel making it simple to use in both bright sunlight and dim conditions.

dB-3908 TWT Amplifier

The dB-3908 TWT Amplifier (TWTA) is designed to use two wideband, periodic permanent magnet (PPM)-focused TWTs to amplify CW, AM, FM or pulse-modulated signals. The dB-3908 offers higher saturated output power and improved harmonic performance when compared to a single TWT approach.

Broadband Matrix Switch: 20-3000 MHz

The MAS4488 is a broadband matrix switch with an 8 input, 8 output, non-blocking configuration. The system itself is comprised of a processor board, an 8x8 matrix, a LAN interface, a redundant power supply, and manual control.

Integrated Digital Control Unit: dB-9004

The dB-9004 integrated digital control unit (IDCU) is designed to operate in the C, X, and Ku-band frequency ranges to provide highly accurate RF output, which can be FM, AM, and pulse shape modulated. The DCU is capable of controlling its internal RF source and other external RF equipment such as antennas and amplifiers.

Remote Spectrum Monitor: MS27102A

The MS27102A is a remote spectrum monitor from Anritsu covering the 9 kHz to 6 GHz frequency range. With sweep rate capabilities up to 24 GHz/s, this monitor is able to mitigate interference problems, and find and identify any illegal or unlicensed signal activity. This monitor can also be used to characterize spectrum occupancy, and enforce compliance in government applications.

Pulsed RF Microwave Frequency Counter/Analyzer: CNT-90XL

This RF/Microwave frequency counter/analyzer can be used to measure, analyze, and calibrate microwave frequency, power, and pulsed RF time parameters like pulse width and PRI. This system features a graphical display and improved control over measurement.

Microwave USB Power Sensor (MA24118A)

The MA24118A power sensor is designed to provide accurate average power measurements from 10 MHz to 18 GHz over 60 dB of dynamic range. The sensor employs a "dual path" architecture that provides (similar to thermal sensor) True-RMS measurements over the entire frequency and dynamic range, enabling users to make highly accurate average power measurements for CW, multi-tone, and digitally modulated signal up to 18 GHz. The sensors have internal and external triggering capability that facilitates individual slot power measurements of TDMA waveforms as well as burst power measurements of periodic and non-periodic waveforms.
