); SAEximRunCond expanded to false Errors-To: [EMAIL PROTECTED] RETRY Hi:
While trying to figure out the O-1814 Rb source I found a 1 PPS signal that's less than 10 us wide. But using an HP 54501A DSO it's almost impossible to determine the period. http://www.prc68.com/I/O1814.shtml If the display is 1,000 dots wide: at 2 us/sq the trace takes up about 4.5 squares or 450 dots, at 200 us/sq the trace takes up about 0.045 squares or 4 dots but the second pulse is way off screen. At slower sweep speeds you can't see the pulse. Are there scopes that allow the period of a narrow pulse to be measured that don't cost an arm and leg? -- Have Fun, Brooke Clarke http://www.PRC68.com http://www.precisionclock.com http://www.prc68.com/I/WebCam2.shtml 24/7 Sky-Weather-Astronomy Cam _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
