Re: [PSES] RF CS High Current Test Level [General Use]

[Price, Andrew (Leonardo, UK)]

Ken

There is no requirement that is flat but there are a few that require such a 
high level 1A, 1.7A, 3.98A over the range 2MHz to 30MHz.

Regards
Andy

Don't know what requirement/limit you are testing to, but a limit that is flat 
below 500 kHz at a level near 2 amps is wrong.

Thanks Ken,

That's the first piece of the puzzle covered, so still looking for 10KHz-400KHz 
and above 10MHz.
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?

Although they don't show a data sheet, you can derive from the max input power 
and insertion loss that it's capable of injecting 2 amps.  But only between 
roughly 400 kHz to 10 MHz.

Hi Folks

Does anyone have experience generating 1.7A CW (10KHz - 400MHz) using Bulk 
Current Injection?

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
