Aren't all those bad things going to happen whether you adjust the C-field or leave it untouched? Isn't the C-field required for the Rb to work dependably and on freq? I think the question pertains to Rb sources that already have a screw to make the adjustment. Maybe you are saying the screw is there to put the C-field back where it belongs. I would have no way of knowing how to tell if it was right or wrong other than frequency.
Rick said it is not a good way to adjust the frequency. I don't really understand why exactly either. > Peter Vince wrote: > >> ); SAEximRunCond expanded to false >> Errors-To: [EMAIL PROTECTED] RETRY >> >> Hi Rick, >> >> >>> Newer Rb units may use adjustment of the internal synthesizer >>> in place of modifying the C-field.
