3 RF Testing Don’ts You Need To Avoid At Every Cost

RF testing refers to radio equipment testing. RF is short for Radio Frequency. It is the frequency lying in the electromagnetic spectrum linked to radio wave propagation. RF has wide applications in communications across various industry verticals such as television broadcasting, establishing computer and mobile networks, remote control, metering and monitoring, and many more. Its biggest advantage is that it doesn’t depend on line of sight for establishing connectivity. It can transfer information between two points without relying on any external electrical connection. Therefore, the ability of the two circuits in the communication loop to catch and interpret each other’s signals plays a crucial role in RF communication. The process of making accurate measurements in RF testing becomes vital as it determines the quality of communication, the precision of readings, and the overall efficiency of the device. Regardless of the sophisticated technology you use for testing such as AEA software among others, here are the top three don’t you need to watch out for from your end.

Incorrect Pathloss Characterization

Practicing too much relaxation while taking measurements for your RF testing is one of the most common reasons for low-quality RF testing. You need to determine the loss of an RF instrument between the signal of interest and your instrument under testing. Pathloss contributions add up to become significant in one-to-one proportion.

Testing with Background Noise

A good isolated environment devoid of background noise is a must for conducting quality measurements. While taking sensitive measurements like phase noise readings even the slightest noise can ruin your reading. Consider good shielding, the lifetime of your RF switch, and look out for signal leakage.

Sticking to Absolute Measurements Only

Well, this stands contradictory to the first point. Sometimes being inflexible around measurements. It is not only time-consuming but can set some unrealistic expectations leading to unnecessary delay in the process. Identify when to switch from absolute to taking relative readings.

Significance Of FDR Over TDR

The concept of preventative maintenance is old. But applied applications of a frequency domain reflectometer are new to routine cable/antenna maintenance. With the introduction of new lightweight and portable instrumentation, FDR-based test equipment has become the best method of installing and maintaining systems. Frequency Domain Reflectometers perform a sweep of frequencies of the transmission line input and then using IFFT (Inverse Fast Fourier Transform) on the reflected signals, converting them back to the time domain. The most significant benefit of the analyzer is that it not only performs the calculations of the DTF from the Vp received but also receives all the reflected signals from the faults in the frequency spectrum. Consequently, it provides the characterization of the type of fault found. Why FDR over TDR(Time Domain Reflectometer)? An FDR can create characterizations of the fault type, which is now capable while using TDR. TDRs aren’t capable of troubleshooting anten

3 Things To Consider Before Getting An Aircraft Wire Harness Tester

Image
Most of us would agree that buying aviation tools is far from easy. Starting from their features to their specifications, you need to focus on many details before you move ahead. As an aircraft wire harness tester is crucial for checking the wiring, you need to ensure that you focus on all the details before making the final decision. One of the best ways to do that is to prepare a checklist of the things you should consider before getting a tester for your setting. Here are some of the things you should consider when you wish to get an aircraft wire tester: 1. Functions of the wire tester First, you should start by focusing on the functions of an aircraft wire tester. Even though it may be used for various purposes, it is primarily used for testing and identifying faults in the wiring system. Ideally, you should go for a wire tester that enables you to locate and fix twisted pairs, single wires in a harness, and all types of coax. In addition to these, you should see if the harness t
