In order to deal with electromagnetic interference (EMI) problems, the source of the unwanted emissions needs to be identified before a solution can be implemented. Testing at an EMC compliance laboratory can prove to be both slow and costly, and oftentimes, the information that comes back from the lab is a spectrum curve that indicates frequencies where emissions are critical of in violation of the limits.
One of the most critical steps in ensuring reliable, long-term wireless infrastructure operation is performing regular preventative maintenance. This application note discusses the challenges of keeping up VNAs for field use, as well as testing processes, adjustments, automation and programming.
This application note provides an overview of the MHL technology and also describes the Rohde & Schwarz compliance test solution for the system part of the current MHL2.0 standard version.
This application note describes Battery Life Measurements with the R&S®RT-ZVC02/04(A) MultiChannel Probe. The measurements are described mostly with the use of an oscilloscope. However, measurements are also possible with CMWRun and a corresponding communication tester.
Both resistive type and reactive type power divider/combiners can be used to fan-in or fan-out RF signals. However, both types distribute RF signals in a different fashion. This white paper offers guidelines and considerations for determining a divider/combiner for each application.
The S331L handheld cable and antenna analyzer is ideal for tower contractors and wireless service providers that need a rugged, handheld field instrument to provide high-performance cable and antenna analysis to ensure optimum deployment, installation, and maintenance of wireless networks.
The 614 Series Digital Signal Booster is a TX RX system from Bird Technologies designed to operate in the UHF frequency band. Digital filters are available for both uplink and downlink, and are user programmable from 6.25 kHz to 1.5 MHz. Other filter center characteristics are fully programmable in order to meet various system and signal demands.
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.
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.
Anritsu USB power sensors eliminate the need for a traditional power meter. These highly accurate, standalone instruments communicate with a PC via USB or with most of the Anritsu handheld instruments (often requiring Option 19). The sensors measure true RMS power, so they are ideal for measuring CW, modulated RF waveforms (e.g. 3G, 4G and OFDM signals) and multi-tone signals. They are ruggedized for field use with an industry-leading +33 dBm damage level.
Bird offers the new IQC91000A Record and Playback System designed for recording modern waveforms for demanding mission requirements in electronic defense systems, and isolating anomalies that occur during system integration and real-world validation testing. The IQC91000A continuously records 90 minutes of 1000 MHz waveforms with its 12 bit fidelity, ensuring the capture of transient and unexpected events.
