Power duration measurements<br />
Power duration measurements record the elapsed time after the introduction of a power step until the output is<br />
attenuated to a safe power level by the onboard protection system (Please refer to page 12 for a full<br />
description). Measurements marked with * indicate loss of output power.<br />
