5 This is a set of example captures of a DCF77 signal. The hardware used for
6 receiving the signal is a Pollin DCF1 module (3.3V supply). The Pollin
7 order number for the module is 810 054.
9 The dumps were made January 9, 2012 in the evening/night.
10 Only the dcf77_480s_pon_interrupted.sr dump was made January 10, 2012 in

22 The logic analyzer used was a Saleae Logic (at 1MHz):

33 The sigrok command line used was:
35 sigrok-cli -d 0:samplerate=1mhz --time 1800s \
36 -p '1=PON,2=DATA' -o dcf77_1800s.sr
38 The time and samplerate varies, depending on the file.
40 The dcf77_480s_interrupted.sr file contains a dump where the power was removed
41 from the module one or more times during the capture.
43 The dcf77_480s_pon_interrupted.sr file contains a dump where the PON pin was
44 set from low to high (PON = high means that the device is disabled) for a
45 few seconds, then back to low.
