What is the Difference Between VNADT and VNAPT?

At first glance, VNADT and VNAPT can appear to be the same thing. But VNADT, or VNA Diagnostic Test, is a basic tool we provided by CMT to verify the functionality of your VNA or ACM. Our diagnosis test will guide you through various tests with step-by-step instructions. Some of these tests are manual and require input from the user, such as providing images of the VNA to check for external damage.


VNAPT, or VNA Performance Test, is an in-depth program that gauges the main performance parameters of the VNA and is typically used by authorized service centers and third-party calibration labs for evaluating the performance of your VNA after repair, or for providing ISO17025 accredited calibration.
