Appendix D to Part 27 - HIRF Environments and Equipment HIRF Test Levels

This appendix specifies the HIRF environments and equipment HIRF test levels for electrical and electronic systems under § 27.1317. The field strength values for the HIRF environments and laboratory equipment HIRF test levels are expressed in root-mean-square units measured during the peak of the modulation cycle.

(a) HIRF environment I is specified in the following table:

Table I. - HIRF Environment I

100 MHz-400 MHz 100 100
400 MHz-700 MHz 700 50
700 MHz-1 GHz 700 100
1 GHz-2 GHz 2,000 200
2 GHz-6 GHz 3,000 200
