Knowing the propagation delays of 1pps signals passing through the Option 133 1pps/ToD/Frequency Converter is critical when setting the Paragon-neos Neo 1pps reference and measurement compensation values.
To minimise the effect of device-to-device variation, users can measure the propagation delays of their specific Option 133 converters using the test sequence described here. The yellow dots in picture below shows the location of 1pps propagation delays in the Rev C and Rev D Option 133 Converter.
KG note – intention is to focus on 1pps propagation delay measurement and not mention ToD delays. OK ?

The functionality of the 1pps paths between ports is given in the table below.
