The example screenshots below show the Paragon-neo 1PPS Time Error Measurement application with appropriate delay compensation, and the Time Error results in CAT. The cables used in this example were 0.64m length at 5.1ns/m gives a Delay Compensation of 3.26ns. The red arrows highlight the relevant status indicators. CAT show the delay through this example Option 133 Converter port3 to port 4 is 18.6ns
...
For future use, ensure that the measured Option 133 delay compensation value is included in the cable delay compensation value when making measurements with it in the signal path e.g. for the above example the cable del value would be the actual cable delays + 18.6ns.
