DCF77 on the Pollin DCF1 module
The dcf77/pollin_dcf1_module directory in sigrok-dumps contains a set of example captures of a DCF77 signal. The hardware used for receiving the signal is a Pollin DCF1 module (3.3V supply). The Pollin order number for the module is 810 054.
The dumps were made January 9, 2012 in the evening/night. Only the dcf77_480s_pon_interrupted.sr dump was made January 10, 2012 in the evening.
The logic analyzer used was a Saleae Logic (at 1MHz).
