The Phillips Laboratory has recently designed and constructed a CW (continuous wave), low-level simulator (ELLIPTICUS) for use in determining coupling of electromagnetic energy to aerospace systems. The antenna is loaded with ferrite beads which have resistors wrapped around them so that a relatively constant resistive load is achieved over a large frequency band. The number of ferrites on the antenna is determined to make the field patterns similar to those produced at the high level pulse simulator, HPD. The HPD simulator with the HAG II pulser was used to measure responses of the same test points on the EMPTAC aircraft which were measured with the CW simulator. How well the responses in the low level CW and high level pulse simulators compare when normalized to similar incident field strengths has been examined
