System maintenance is an integral part of test engineering. Whether you are designing a new test program set or working within an established one, it’s important to keep resources for both preventative and corrective maintenance in mind. By having plans for both addressing equipment issues as they come up and preventing issues from occurring in the first place, your system will be spared from expensive delays in the future. With a specialized focus on National Instruments parts, Apex Waves is able to provide the repairs you need to maximize the performance of your equipment and system.
It’s no secret that software is key to creating the foundation of modern technology. With the rate at which new products and features are introduced into today’s market, the test software industry must prioritize expedient production and flexible customer delivery. How can this be accomplished? Through the standardization of test equipment! For years, the goal of testing organizations has been to achieve standardization- yet many businesses struggle to apply test standards because they can’t agree on how. However, test standardization does not have to entail a major revamp of your engineering and production testing processes. Smaller, more manageable standards, such as code or data management standards, can be implemented to address and resolve inefficiency issues.
All electromagnetic current meters function on the basis that the intensity of the magnetic field around a coil is proportional to the amount of current flowing through it. Whether the meter you are using is alternating current (AC) or direct current (DC), knowing what to expect from the different meter movements is essential for correct calibration and accurate measurements.
Supply chain management is a critical part of any business, but it becomes even more invaluable in times of crisis. In February 2022, the U.S. Department of Commerce and the U.S. Department of Homeland Security published a collaborative report assessing the current state of the supply chains that are critical to the ICT industry. Their findings point to crucial gaps in this vital production process- gaps that Apex Waves is stepping up to fill. When it comes to vital test equipment components, Apex Waves maintains a large inventory of previously used, calibrated, and quality tested parts that are available and ready to ship. Because of this, important parts remain accessible for the industries and businesses that need them most.
Displaying readings on an analog scale, where the digital characters are printed on the scale in the different locations that the pointer swings is not an issue. But, putting digits on a digital readout where different digits must share the same location, is more difficult. Three ways have been used: the solid character, the dot matrix, and the bar segments. The solid character can be the most pleasing way of displaying digits, but it is problematic since they must all share the same space. This was the way the servo wheels worked, and electrically, it was done with Nixie tubes. These used ten transparent in-line wafers enclosed in neon gas. Each wafer had electrodes in the shape of numerals, which glowed when the wafer was electrified. Although the unused wafers were still discernible while one wafer glowed, it was tolerable. The Nixie tube was used for years and can still be found on special equipment. However, this method is costly and the tubes are fragile.
One of the probe types that can be used with an oscilloscope is a passive-voltage probe. The simplest passive-voltage probe is a coaxial cable. But what happens when a coaxial cable is linked to the device under test? A schematic diagram of the test arrangement is given in Fig. 4.1. The device under test is symbolized as a signal source with an internal source resistance Rs.
The ongoing transformation of existing cellular communication networks to fully operational 5G status seems to be progressing at a snail’s pace. Of course, when users dream of the promised data streaming speeds with virtually no latency and comprehensive coverage, it cannot happen fast enough. 5G absolutely has the potential to unleash a veritable new industrial revolution, as well as improved communications on every level.
Tektronix is a globally-recognized source of equipment for engineers, scientists, and technicians. Known for their innovative measurement technology, they have created tools like oscilloscopes that have aided in the advancement of fields like health, communication, and space science. There are new discoveries in science and technology virtually every day, so it’s imminent that what used to be some of the company’s greatest products are replaced with newer, upgraded models. But just because they’ve been replaced doesn’t mean they’re forgotten. Here are some of the best discontinued oscilloscopes from Tektronix.
Keysight is an American technologies company that creates hardware for multiple types of field instruments and produces electronic design software for aerospace and defense engineering. Recently, they signed a Memorandum of Agreement with three prestigious Vietnam universities to support rising engineers. But they aren’t just preparing the way for Vietnamese students. Keysight is creating industry leading engineers at American universities from Pennsylvania all the way to Hawaii with these seven types of services and support.
To prevent interference on receiving apparatus, for example, audio and TV receivers or computer systems, signals generated in the line supply and the radiated electromagnetic field of radio frequency from electrical equipment may not exceed certain limits. For this, the IEC makes recommendations. A special committee of the IEC, the CISPR (International Special Committee on Radio Interference), has published several definitions concerning measuring sets and measurement procedures for the various types of interference-producing equipment.
