That won¹t work. Consider that the CS114 / RTCA/DO-160 section 20 method requires pre-calibration in a 100 ohm calibration fixture. At 1.7 amps, that means 170 volts into the fixture.
The requirement is overkill, by many orders-of-magnitude.

The OP seems to need/want a clamp that will inject 1.7 amps at 10 kHz, and into the calibration fixture 100 ohm load, that is just flat wrong.

Not sure if Fischer have a full solution for this but will ring them back to see :-) Does anyone know of other vendors who may be able to help?

But only between roughly 400 kHz to 10 MHz.

Wondering how people have achieved it, is there a BCI on the market able to sustain this level "off the shelf" or a vendor who custom builds them? A possible alternative was to use multiple BCI's and a Power Splitter, but I can see this problematic at higher frequencies due to wavelength/phase etc I realise that you would need separate BCI's, splitting the test into frequency bands as no one BCI could do it all Thanks for any help provided Rich - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
