BTS System Line Sweep And PIM Testing
Line sweep testing and PIM are very different tests. Both are very important and accurate measures of a cell site's ability to provide service and perform optimally. Read the white paper from Anritsu.
How To Measure 5ns Rise/Fall Time On An RF Pulsed Power Amplifier By Agilent Technologies
Rise/fall time is one of the key measurement parameters when designing, manufacturing, or maintaining pulsed radar power amplifier systems, especially for wideband pulse power amplifiers. Learn how to achieve 5 nanosecond rise/fall time RF pulse measurement with the 8990B peak power analyzer by reading this application note. This article also includes tips on how to consistently obtain accurate rise/fall time measurement results.
Troubleshooting Passive Intermodulation Problems In The Field By Nicholas Cannon, Anritsu Company
It is broadly understood that passive modulation is a formidable issue within the cellular industry, resulting in poor site/sector performance and reduced coverage. Testing for PIM is now required in the field.
The Wideband Power Sensor Family From Bird Technologies Group
• Includes multiple units to cover the entire 25- to 4000-MHz frequency range and 25-mW to 500-W dynamic range.
• Easy to operate with a wide range of display devices, including the free Bird Virtual Power Meter application.
• Never requires field calibration, only requires calibration once per year and is traceable to National Institute of Standards and Technology (NIST).
Founded in 1979 in Beech Grove, Indiana, JFW Industries Inc. is a world leader in designing and manufacturing passive RF components and application specific test systems. These components include attenuators, RF switches, and specialized test systems for use in the cellular, telecommunications, OEM test equipment, medical, automotive, defense, and automated test markets.
The TM series "RF Orange" cable is a cost-effective solution for numerous production or general-purpose test applications. The GrooveTube technology offers excellent phase and amplitude stability with flexure.
KEC, a UK manufacturer of EMC interconnect components and cable harness assemblies, strengthened its market leadership and differentiated itself from the competition by offering a unique technology. Using Remcom’s XFdtd to model and simulate customers’ designs, KEC can identify problems early in the process and recommend corrections before the EMC certification stage.
This video interview explains the basics of passive intermodulation (PIM) including what PIM is, what causes it, what the symptoms are, and how to find it using the new Anritsu MW8219A PIM Master solution with Distance-to-PIM technology.
