When manufacturing the cells for the 5065A receiver package it was not feasable or cost effective to try and make each cell exactly on frequency.
With the sythesizer designed the way it was all thay had to do was make sure that cells would fall within the 0 to +1000X10-10th range. That way they could be tuned to zero via the synthesizer and C-field. This would also allow corrections if the time scale was changed. Early standards like the Varian 4700 or early R20 units did not have synthesizers. If the time scale changed you had to send the whole instrument back to the factory and they would install a new cell made to match the time scale change! The 117A had a companion unit that had a motor driven 100khz phase shifter that would turn at a rate to match the new time scale. If the time scale changed you ordered a new gear from HP to make the rate match! Corby Dawson ____________________________________________________________ Refinance at 3.25% FIXED!
