Our life cycle management program assures you of a dependable, quality source of obsolete IC's forever. No mention that the price may go up exponentially each time you ask for a quote, and don't try to buy two dozens. They probably won't make a run for much less than several thousand pieces, and

I have fielded two dozen pieces of equipment with 2x16 VFD from Noritake. These are on 24/7 and they were shipped over a 4 year period starting in 2000. In normal state, there are 4 digits always turned on on the first line. The other digits are rarely turned on. The displays start being

I am there too. I have used ExpressPCB because it is actually very fast and easy for small projects. I also use the schematic capture for illustrations (when I just need a schematic, no PWB) because it also makes decent looking schematics without fuss. Creating component models bot both schematic

Re: [volt-nuts] What really gets calibrated?

The big difference is that nowadays, adjustment is done in software without moving parts. There is no wear out involved in doing frequent adjustment and through the software you can record by how much each setting was adjusted. These were the main reasons for not adjusting an instrument that
