I started working on my 58517A splitter yesterday. After looking at the board, I don't think installing a simple 0-ohm shunt to the GPS port is the right way to enable thru power. If you do that, port 1 will go directly to a bunch of bypass capacitors, and I doubt you'll see any signal

If you don't need NI488.2 compatibility and you don't mind configuring it yourself in HyperTerm (the new version no longer has DIP switches), the answer's yes... that's not a bad price at all for a USB-GPIB dongle. Even the used NI ones commonly sell for twice that. -- john, KE5FX

Is this worth the $150.00? Sorry, I meant to point out that the old version was only $125. :) What do you want to do? I'm happy with mine, but then I like low level hacking. If you like Linux, take a look at the sample code I wrote. http://www.megapathdsl.net/~hmurray/hacks/probe.c A few

At the end of the USB cable there is a FTDI chip that (in conjunction with the appropiate driver) emulates a serial port. This serial port in turn is connected to the serial port of an AVR type of microcontroller. Because this microcontroller expects a certain setting of serial transmission
