Hello, In my copy of RTCA DO-160E it is 1 kHz. Version F will be the same, I believe.

From: [email protected] [mailto:[email protected]] On Behalf Of Ken Javor Sent: Wednesday, August 08, 2007 4:19 PM To: [email protected] Cc: Group, IEEE EMC Discussion Subject: RTCA/DO-160E Section 21 emission measurement bandwidths I am measuring dc/dc converter emissions against the RTCA/DO-160 section 21 CE limit (class L). Above about 20 MHz, there are some BB emissions. If I use a 9 kHz BW, they just fail. At 1 kHz BW, they pass. My copy of RTCA/DO-160D says to use 1 kHz BW over the CE frequency range (0.15 - 30 MHz). That seems kind of low to me. Can anyone confirm the same bandwidth is used for DO-160E as well, or if it has maybe increased?
