To monitor paging signals, several options exist.
Option 1: PC with soundcardThis only works for 2-level signals. You'll need:
Under Windows XP and higher, fair to good results can be achieved, but success is not guaranteed. Both the quality and settings of the soundcard and the settings of PDW impact the performance.

A built and tested USB interface can be ordered through the Order Page. The RS232 interface has been discontinued.
Option 3: PC with a 'slicer' interfaceYou'll need:
