HP 3390A INTEGRATOR FREE
It´s free but you have to catch it here in Switzerland I think, I still have one, I don´t need anymore. Message #4 Posted by Matthias on 8 Sept 2004, 7:38 a.m., It's the one used in just about all the HPIL peripherals. Yes, the 1LB3-0003 is an HPIL controller/interface. Message #3 Posted by Tony Duell on 8 Sept 2004, 1:07 p.m., The device for itself is not too exciting, but the parts may be handy someday. It has the "name" ILB3-0003 and may be a controller for the HP-IL interface.

There is also at least one circuit made by HP. Inside there are several microcontrollers (i8031, SCN8051, D8049), most of the circuits are LS-TTL. The case is very difficult to open, it is probably impossible to do this without traces. There there are three multi pin connectors at the back for the connection of some other device and a HP-IL interface It seems, you can do with the device alone not much, besides running the self test. I have a similar one, a HP 3392A, but without any documentation.

From what I could find on google, it is used to integrate measurements from other equipment in a chemistry lab. Message #1 Posted by John Limpert on 8 Sept 2004, 5:04 a.m.Īnyone ever run into one of these gadgets? I saw one listed on eBay and it looks a bit like a lab calculator.
