Hi, today I heard about a case where an ISDN terminal was susceptible to a DECT phone next to it while a 900 MHz GSM did not cause anything. This was in the field, not in test lab. In test lab my experience is that if it passes below 1 G it does it also above it. However, as the 1.4-2 GHz sweep takes very short time we haven't bothered with this, just testing to avoid guessing. regards Ari Honkala > -----Original Message----- > From: ext [mailto:am...@westin-emission.no] > Sent: 10 January, 2002 13:07 > To: emc-p...@majordomo.ieee.org > Subject: RF immunity 1-2GHz > > > > RF immunity testing in the frequency range 80-1000MHz has > been common in EU > for several years.
