Title: DIY low cost HP/Agilent 53131/132/181 Timebase
Post by: gamalot on March 24, 2017, 12:43:33 am

STM32F030 MCU is used as serial interface A/D D/A converter instead of the old expensive AD7243.

I have made a prototype and tested it on all three models of 531xx series, it works.

If the ocxo is tuned from a DAC then there is no option for locking to an external reference?

No, but there will be an additional item in the calibration menu.
