I've got an antique EFT simulator, it's a KeyTek CE-40. I'm debugging a device for EFT as per EN 61000-4-4. The manufacturer doesn't provide support for the device anymore and I don't have a product manual.
As per the standard, the burst duration should be 15 ms.
When I go to the device burst duration setting, I see some weird time symbol that is not in "ms" -- picture is attached.
Does anyone know what the time symbol they are showing there is? Is it a microsecond?
