Both tests are aimed at preventing unwanted interference with commercial radio and television reception. Several vendors now offer a combination of these two that eliminate the need to switch antennas. You'll also need a non-conductive tripod to hold the antennas. The test site can be simple, too. Be sure to use a ground screen under the test area, and stay at least 3 meters from any reflecting surface.
Ambient signals can cause problems.
While we've done these tests right in the engineering lab, you may be jammed by other similar equipment. This is another good candidate for pre-compliance testing. We recommend using IEC 801.2, the test method specified by the European Union. This document describes the test procedures and recommends test levels. Two caveats about ESD testing.
