Help! When we inject as per IEC 61000-4-6, the 1 kHz tone is demodulated and is VERY loud in the telephone earpiece! This happens no matter which i/o cable we inject, even the power cord. The conducted RF appears to re-radiate inside the chassis and is being picked up by the line card. We use an AMD/Legerity Am79R70 chip, it is very sensitive at the RSN pin. Has anyone experienced similar problems? Has anyone passed this test with this chip, or with another?
Thanks in advance, David. David Gelfand Regulatory Approvals Memotec Communications Inc.
