Well RF chamber is already luxury. Cheapest thing is RF tent. Like TekBox from Tektronix. A tent is perfect solution to get testing quickly and cheaply. RF chamber needs some commitment - dedicated office space and big chamber needs in addition some time for installation.
- mrWiz 3y agoA while back we had a skunkworks project that needed to pass CISPR 11 but also had ~0 budget. Initial testing in a rented chamber revealed a grossly-failing amount of energy emitted that had a clear peak but covered a fair bit of spectrum. The solution was to head out to a nearby field and set up a Yagi antenna at one end and an easy-up and generator to power the device at the other. This allowed a few months testing for ~free, and with a fast loop of "iterate design" -> "retest" -> "repeat". It wasn't great testing, but suitable enough to tell if the frequency we cared about was improving and by how many dB.
