> Is this calibrator gated?
Back in the stone age when I started work, a CRO (with a 5BP1 tube in it) was calibrated in time by a gated oscillator that put little pips on the trace at 1 microsecond intervals. So that the markers would not crawl across the screen the oscillator was stopped and started for each trace so as to be in phase with the synch pulse. The CRO was probably 1950s vintage, I was using it in 1961 for calibration of navigation radar. The CRO tubes were very non-linear so graticule divisions were not accurate enough. cheers, Neville Michie > _____________ > 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. _______________________________________________ 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.
