Teardown fake USB-GPIB-HS from china

[@gondala]

I think no matter it is fake or original, as long as it works for our need, then it's fine to me.

[@decee1157]

I do agree. I was just very curious about the differences of a fake and an original device.

If you integrated the fake one then sold your system to your customer and commit that you are using the high quality GPIB-USB from NI, you are doing wrong. If you told the customer that you are using the fake one to build the system and your customer is okay with that, there is nothing to concern.

@@bboytyphoonllg i think the price says everything, your customer know if you sell cheaper then they won't expect original.

[@bboytyphoonllg]

@@gondala If you sell single part, the customer will see the price but if you integrating to a system, the customer won't know.

It is risky. I have a customer who was using fake one for production. It was running great in the beginning, but later many systems got troubles. At that time, no one could help. Using fake one is putting users into a risky situation. I would rather choose used but fake.

Does it work ok? Does it work with Windows 10? Do you need some specific software to use it? There are several ebay suppliers at around US$100, does that seem to be in the ballpark you paid?

I just (unknowingly) got a counterfeit one from Newegg. It worked with windows 7 NI MAX software, but errored out when I tried to use it with Flukes Met/Cal software.

It works just fine, it just needed the official driver package

Chinese also make a fake Keysight GPIB-USB adapter complete with Keysight CD (who knows what spyware you are getting from it). Everyone of those sold on eBay as new is a fake. Mine broke down in less than a year. You get what you pay for. The real Keysight adapter has deep knurling on the tie down screws.

if its working fine then why its fake.

[@decee1157]

Fake does not mean it doesn't work. Problem with many fake devices is that they might work great but then there are some edge cases where you spend countless hours troubleshooting only to realise it is caused by the device being fake.

[@chaimguzman7620]

If you have a brain doesn't mean you are not a MORON.

National Instruments (NI) has been changing its drivers to recognize fake items and won't communicate with them. A machine with the old drivers will work fine so long as you never accidentally update them. A new installation however is a PITA to get working with fake hardware, as NI hides the old versions of the drivers; iirc you have to search for a hidden legacy installer that can see those versions on the NI servers.

@@pvnbunny I haven't realize it is so tricky, considering it is all very old technology. I need one GPIB-USB converter as I would like to experiment with an old Tektronix spectrum analyzer, which was a gift. There is no waay I am buying an original adapter, as some of them cost I can almost buy a simple spectrum analyzer, hahaha. But I understand, the sellers have those obsolete stuff laying around in a corner, and from time to time some people are obviously willing to pay for it. Maybe some companies with some specific setup's.... I see Elektor has a DIY project, but the cost of that all together could be more then a fake adapter. The question is if I can use that fake adapter with LabView, as I would like to write some GUI for the spectrum analyzer...
