Paragon-neo: Balanced/Unbalanced 1PPS Inputs

Changes were made to Paragon-neo’s 1PPS qualification logic between R10 and R11 releases.

R10 (and earlier) allowed the signal to have a wide range of duty cycle, but in R11 the timing requirement was tightened to be compliant with the G.703 definition of a 1PPS pulse:

• Min pulse width = 100ns

• Max pulse width = 500ms

The requirement applies to the 1PPS reference and measurement inputs, both balanced and unbalanced.

Please refer to the Paragon-neo Getting Started Guide for further details.

Here’s a copy of the relevant data for the 1PPS measurement inputs from the R11 Getting Started Guide:
