Completely unplugged on the GPIB side, it took 2 to 3 tries of unplugging and plugging the USB to get through enumeration. --- End quote --- Since this adapter is powered from USB, could its firmware possibly was not properly negotiating the power with the computer, or consuming over 500mA so the computer could not do it. |

--- Quote from: dadler on August 19, 2015, 08:26:34 am ---As promised, here are pictures of the Clone unit I purchased for $51 shipped @ http://www.ebay.com/itm/82357B-GPIB-USB-Interface-Compatible-AGILENT-82357B-new-version-/251692772284 I actually think this one is higher quality than the faux-"Agilent" version that I paid ~$130 for. The circuitry is clearly different, though. Seems to work fine in BenchVue. For the price, I think this is a pretty good deal. I've only played with it for about 30 minutes, but seems ok so far. I really am surprised that they can blatantly sell products with the "Agilent" name plastered all over them, and not get hassled by Agilent/Keysight? A few more pictures: https://www.dropbox.com/sh/kse4k3pw103qaq9/AACxiQPkh3lCRIQAjZYc2R6Ha?dl=0 --- End quote --- Dadler, your last photo shows the interface connected to your test equipment with a cable but presumably the interface could plug directly into the test equipment without the cable? And it should work with GPIB and "HPIB"? Thanks, EF |

I just opened one of my Agilent 82357B to see if it is real of fake. Based on what I have seen in some pictures in this thread, the soldering in my item looks real genuine. What do you think? |
