This includes: Precision regulators for DC supply. 24 bit DAC Reference for DAC All analog devices, resistors and capacitors after DAC. All buffer amplifiers from oscillator. Unit only has raw DC and I2C lines for inputs and 5MHz sine wave out at 3 volts p-p. It also seemed the obvious way to go in the design. Performance is difficult to measure with equipment on hand. Waiting on funding for experiment which includes equipment traceable to NIST. _______________________________________________ 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.
