RE: DIY Equipment and Calibration

If you do your own calibration you need to follow the requirements in ISO 17025 for calibration labs. This requires that you calculate your measurement uncertainty, where a test alb is only estimating the uncertainty. Best Regards Lothar Schmidt Director Regulatory Antenna Services CETECOM

The reason for the 1.8 factor is that you are calibrating with a CW signal. When you switch the modulation on in real testing the peak level for the amplifier will be in the range of 1.8 of the CW level. It’s just a pre-caution not to overdrive the amplifier. Best Regards Lothar Schmidt
