Homemade Wideband Current Transformer

I use a Prologix GPIB-Ethernet, connected to a wireless bridge on top of my rack full of boat anchors. Works great, no cables to worry about, just turn it on and forget about it.

Cheers

GPIB is exceedingly complex. BUT If you have a modern instrument that's programmed in ASCII, it takes zero understanding of the protocol. A PIC processor can easily copy ASCII between RS-232 and GPIB. And you can plug on a RS-232 to USB or Bluetooth adapter and get anywhere you want.

Doesn't meet ANY standards. Doesn't look pretty. It ain't fast. But it's cheap, it works and one chip fits in a gender-changer dongle.

At $80 shipped, it might be worth the gamble.

it works in IE 9 for me, but you may need to force these headers

Content-Type: Coontent-Disposition:

for the last one, you'll have to fiddle with forced download options and set a file name, otherwise some browsers will think the file is just file.php

also, the behavior in browsers can differ if you click on a link or try to save target as. Saving target as can cause problems.

OK, thanks for the hints. It should work better now.

No problem. it seems to "pass" some quick tests for making browers know it's a tiff and a file.
