--- Quote from: Macbeth on August 16, 2015, 10:51:51 pm ---My attempts at getting the 3 lowest price sellers to counteroffer led to one bowing out and the other two ending up at $80 including delivery. Now I don't need one of these as I am happy with USB-TMC and RS232 at the moment, but I am sure I will pick up some gear in the future that requires GPIB. If the non-fake but still a copy device is going for $51 (+ $10 P&P) then that seems the better deal to me. I really do not want to reward counterfeiters with any premium. Blatant copiers I'm ok with. There is a difference. Also the likes of Agilent & NI need shooting for their absurd prices. --- End quote --- I actually got them to accept $51, postage included (DHL Shenzhen->USA) |

I've just opened my unit up. Excess flux around the agilent chip, the cypress chip and the xilinx chip too. Everything else looks squeaky clean. It is a heck of a lot of effort to go to for a item like this. I will fire up the old workshop computer (The only windows PC I have) and give it a quick whirl to see if it works or not. |

Companies like Agilent have a extreme high respect to their Logo and proper printing of it in the right colors, sizes and fonts. On several of the pictures show here i can see that the Alignment of the blue Agilent Star in respect to the A does not fit. Its right line does not point to the middle of the A in the word Agilent. Furthermore if you compare the Agilent on the PCBs you'll see that the counterfeit-parts are not using the correct font. I would not expect Agilent to produce something with a wrong logo on it, so it must be counterfeit. Where i am not sure is the Agilent logo printed on some of the chips in the pictures shown here. It looks like the letter spacing may be wrong on some of the pictures. |

I have a fake 82357B, which doesn't try to hide; just a square gold box with a sticker saying 82357B GPIB-USB controller. I tried to get it to run with the applications i'm using (EZGPIB, Timelabs) but ran into problems. No idea if it was due to the adapter or the HP suite (or the combination). Now using a prologix. The inside of the box is not that interesting; all of the chips and even other components are hidden under black epoxy. Nothing to see. But the soldering job is pretty good compared to what i see here. |

I bought a few of these over the last few years and never had any problems with them and never suspected anything wrong, even when the price was low. But now I am tempted to open all my units. |
