Evaluating Calibration Tolerances Can Save You Trouble
Is Losing Business Worth the Risk? Having an instrument not meeting specifications is bad for the owner or operator of an instrument and bad for the manufacturer. It can be costly. The owner may need to take special action to mitigate the problem, perhaps even recall work done. The manufacturer may lose customers’ trust. Clearly, it is a situation to be avoided. Without due consideration, out-of-tolerance conditions may be much too likely to occur.
Troubleshoot Microwave & RF Problems
Troubleshooting Microwave & RF Problems Using Insertion Loss Measurement Understanding the Role of Transmission Line Performance In any wireless communication network, transmission feed line performance directly impacts signal quality, system reliability, and coverage range. Faulty cables, connectors, or antennas can quickly degrade network efficiency, causing dropped calls, data loss, or costly downtime. Insertion loss measurement is one of the most effective diagnostic techniques for assessing the health…

NIST Numbers… What Are They?
What is the official NIST Number on my report? The official NIST number, or the number that NIST uses to keep track of reports, is a long number containing the number for the Division performing the service, the number the NIST Calibration Program Office generates, and the year the service is performed. This number should be on every page of the report. For example, a typical number for our Division (821) is 821/123456-97. Many reports will…
