There are custom apib-usb interface for system one and system two
AMD the ATS-2 wbich i consider had oem interface usb

As for the UPL prices, ofc ther are a lot of units for the price approx 2000-2500 dolars, but they are older with clearly signs of thousands hours of usage

Yes, and the USB adapter is often $300+ and may not work on a modern OS (still needs drivers).  It can probably be done in an XP VM, but it's another layer of complexity to the system at a fair percentage of the price for the unit, so it's at least worth considering.

Not sure why you think this UPL is newer - they haven't made them in 20 years.  Expect it to have just as many hours and a similar age to other units - if you get a Windows 95 based unit, you have a new one, a good number were DOS.  That said, from the lack of yellowing from the plastics, this one probably wasn't kept near a window.  Yes it looks nice and was probably well cared for (wouldn't be surprised if the LCD or backlight is just a new replacement), but that doesn't mean you're getting a newer instrument.


Not sure if there's availability, but the Prism Sound dScope III is a pretty capable USB Audio analyzer that probably still has its software package downloadable from the manufacturer.  I think the overall specs are a little lower, but if you're considering the host computer route, it's somewhat newer and has a much smaller bench footprint.  The QA403 is a reasonable choice, especially for the price, and its software is pretty fully featured.  I could be wrong, but I believe the UPL and AP analyzers support higher input voltages, so for some kinds of testing they may be a better choice than the other units.  It could also be worth identifying any specific measurements you need that may not be usual - I remember an audio tech complaining about the UPV for removing some of the record player specific measurements that the UPL had, and especially if you don't want to be trying to do your own scripting, having those built in could be a big value proposition.

1996 was the launch date, and they were produced till 2008, im getting information about them since few weeks.

About the AP, software is downloadable from site, and the interface is working under win 10 and 11
I have already tested in demo mode, what is also advantage of AP is the automatic tests, "HST" which are all measurments made 1 by 1 and reported in similiar way to RMAA soft.

I work on a lot of hi-end stuff like Krell power amps, Mark Levinson power amps so the capability of high voltage input is welcome.

Bought UPL with B1 option

Hello i just bought the UPL from a test equipment company, they tried to change the disk for ssd but it doesnt work.

They had transcendar 64GB ssd and from what I read these discs were not working.

I ordered CF adapter and 4GB card, after I receive unit I will make disc image from this ssd to CF and hope it will work.

The original spinning disc is 20GB fujitsu from 2003 year
