Logic analyzer setup
--------------------

The logic analyzer used for capturing was a Saleae Logic.

The logic analyzer probes were connected like this:

  Probe       DCF77 module
  ------------------------
  1 (black)   PON
  2 (brown)   DATA
  GND         GND


Data
----

The sigrok command line used was:

  sigrok-cli -d 0:samplerate=1mhz --time 1800s \
             -p '1=PON,2=DATA' -o dcf77_1800s.sr

The time and samplerate varies, depending on the file.
