HERO SUPPORTING STUDIES
Abstract
Evaluation tests intended to extensively characterize hot wire bridged EED have been outlined. This includes tests for both dc and RF functioning sensitivity. Tests to determine the rate of change of resistance with temperature, the RF cook-off power, and the effect of low eve dc or RF excitation on normal functioning responses round out the program. Analyses are being made of errors to be expected in rf power measuring systems. The directivity errors associated with use of directional couplers to measure incident and reflected power are developed. These errors, both of which approach a common value of 2% for couplers with 40 db of directivity combine to give a possible maximum error approaching infinity.
