In the first part of this series, we saw that using an attenuator in a high RF power measurement scenario posed several disadvantages and may require quite a bit of effort to minimize those problems. So, is there a more robust and advantageous method to perform high power RF measurements with your power meter? The answer is yes.
Power is perhaps the most frequently measured quantity in RF measurements, typically done using an RF power meter. What do you do when you are armed with a power meter (rated up to +30 dBm) and have to measure the output power of a 100 W transmitter? Intuitively, you might try to plug in a high power fixed attenuator to bring the power down to a safe level measurable by your sensitive power meter. Sounds sensible right? On the contrary, you may find yourself getting frustrated over unstable and inaccurate power readings.
Cable faults can happen both during site installation and over time. Despite the best effort to protect these cables, they are still susceptible to the various environmental stresses and sometimes, extreme weather conditions. Eventually, degradation of cable performances or even physical damages occur. Since the combined length of the cables between the antenna and transceiver equipment could reach hundreds of feet, the sooner you know where faults occur along the line, the sooner you can resolve the problem, and the better your customer satisfaction ratings.
Power supplies are such basic tools, with many options commonly available to consumers, that it’s easy to overlook their finer points. For example, many include multiple outputs. Also, multichannel units with high output accuracy are available at increasingly economical prices. Still, no equipment budget can afford every “bell and whistle” so it makes sense to determine which applications really demand a multichannel power supply and which ones don’t. Here, several questions to ask when determining your power supply needs.
Test and Measurement Equipment (TME) Management is a term that begs the question, “What do you mean by that?” There are a variety of definitions for the term. What exactly does TME Management entail? Most answers include a combination of management, financial, economic, engineering and other practices applied to provide the required level of service in the most cost effective manner.
A good TME Management process should include the whole ownership life cycle of a product and should involve acquisitioning, commissioning, certifying, calibrating, tracking, operating, maintain, repairing, modifying, replacing, decommissioning, and disposal of physical and infrastructure assets. Does this all sound a bit familiar? If so, you’ve been here before, haven’t you? It’s exactly Measurement Assurance Technology offers to our customers: a one stop solution.
When working with test and measurement in general, mechanical fixtures and software seem to attract the attention of many engineers. Not everyone has a regular need for advanced electrical engineering tools though and if that’s your case, it’s probably hard to justify buying expensive EE tools with very specific functionality. This is another time when open-source software comes to the rescue. Here, three programs that should help you stay on top of your work without having to pay the hefty prices that are attached to the advanced software.
Calibrating, Servicing and Selling Electronic Test Equipment means we care about the quality and reliability of our products as much as our customers do. And, like our customers, we’re concerned about the cost of ownership of the tools we sell. Read on for ways in which you can buy and operate with assurance...
