Cable Loss Effect on System Return Loss
The insertion loss of the cable needs to be taken into consideration when making system return loss measurements using portable cable and antenna analyzers like the Anritsu Site Master S331E & S332E. The picture below(picture 4) illustrates how the cable loss changes the perceived antenna performance. The antenna itself has a return loss of 15 dB… Continue Reading »
The Out of Tolerance Solution
We had two BK4010A generators in for calibration in the JM Test Alexandria Lab recently, and all parameters except one were well in tolerance. The out of tolerance condition was the Voltage Controlled Generator(VCG) frequency section of the verification.
Briefly, the verification consists of the following:
Set the Frequency Range to 200 kHz, and the dial to 2 (setting the frequency to 200 kHz). Apply a… Continue Reading »
The cable and antenna system plays a crucial role of the overall performance of a Base Station system. Degradations and failures in the antenna system may cause poor voice quality or dropped calls. From a carrier standpoint, this could eventually result in loss of revenue.
While a problematic base station can be replaced, a cable and antenna system is not so easy to replace. It is the role of the field technician to troubleshoot the… Continue Reading »
Guide to Choosing the Right Cable Test Tool to Meet Your Testing Needs
New cable test tools, designed to perform various tasks at various price ranges, are emerging at a rapid rate in today’s competitive market of cable test equipment. All cable test tools are useful for specific applications and users, but not all meet TIA/ISO performance standards and certification warranty requirements. It’s important to… Continue Reading »
This white paper explores the state of the cabling industry – where it has been and where it is going. It evaluates what it takes to succeed in the face of an exponentially greater need for cabling contractors to manage multiple environments, media, standards, and technologies. In this new multi, multi, multi world – the new normal – what do cabling… Continue Reading »
Whether installing new cable, or troubleshooting existing cable, cable testing with a unit like a Fluke Networks DTX-1800 plays an important role in the process. Common tests for datacom cabling include length, wiremap, attenuation, NEXT, DC loop resistance, and return loss.
As networks evolve, so do the requirements of the cabling infrastructure to support them. New standards are continuously being developed to provide guidelines for cabling professionals when installing, testing,… Continue Reading »
Site Master – Introduction
Transmission feed line system performance plays an important role in wireless network coverage. Insertion loss measurement is one of the critical measurements used to analyze transmission feed line installation and performance quality. This application note explains how Anritsu… Continue Reading »
What’s the problem?
Fiber optic cabling carries pulses of light between transmitters and receivers. These pulses represent the data being sent across the cable. In order for the data to be transmitted successfully, the light must arrive at the far end of the cable with enough power to be measured. Light loss between the ends of a fiber link comes from multiple sources such… Continue Reading »
