Yes, the emissions peak is at about 67Mhz and it's quite broad band.
That doesn't really matter to me where the noise is generated, it's not my product to fix. All I know is the new Itech AC power source has horrible radiated emissions, more than 17db above the AS61000.6.3 limits for commercial, residential and light industrial environments, so I can't use it for pre-compliance testing of the products I'm trying to develop. The earlier model BK9801 (Itech M7321) is fine for that purpose, no appreciable radiated (or conducted) emissions at all. So the new Itech product is not fit for purpose, if it doesn't comply with mandatory EMC requirements it shouldn't be sold here. I'm just trying to determine what the mandatory requirements for test equipment such as this are for Australia ?
