Re: Yokogawa Hewlett Packard Message #4 Posted by Ellis Easley on 2 May 2003, 1:04 a.m., in response to message #3 by Gordon Dyer
David Packard talks about YHP in "The HP Way" in a section about quality. It was HP's first joint venture and the Yokogawa company had been in the business of "process instrumentation". Could that have something to do with analog computing? I have a universal bridge from Yokogawa HP. The heart of it seems to be an enormous precision potentiometer that is connected to a very long dial, it must generate a voltage that models a complex function. We had a computerized network gain-phase analyzer at Tandy that I think was from Yokogama HP. I remember using it to plot the frequency response and calculate the equivalent circuit of quartz crystals - they would have inductances of hundreds of Henrys and minute capacitances. Packard also talks about an HP facilty in Boeblingen, Germany, which was part of HP's first steps to distribute their products in Europe. I have two pulse generators built in Boeblingen including the 8005B - I always wanted that one because it is frequently mentioned in the test conditions section of semiconductor data sheets.
