Yes, it's the same M12; other M12's are similar. VP's have the same thing but the peak-to-peak is larger. This is all normal and the sawtooth does not indicate anything is wrong. In fact, you can make a good case that the noise of a 1 PPS sawtooth is a good thing in many cases; as we found with Tom Clark's original TAC, it permits simple time interval averaging to give a more precise result in spite of the 1 PPS quantization. Not sure what you mean by a short time. The web page dates back to Nov 2004, I think. But the sawtooth in this and other receivers show up in a matter of seconds so it's not like you have to take a lot of data over a long time to see it (note that most of the plots on that page cover only 2 minutes of elapsed time). /tvb _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
