[time-nuts] PRS-10 input and output calibrations

[Magnus Danielson]

Fellow time-nuts,

Anyone who has tried to calibrate the PPS input and PPS output 
interpolators of the PRS-10?

The output calibration seems pretty easy to do, just a TIC to measure 
the PPS to 10 MHz and then sweep through the output delay values to 
cover a little more than the 400 ns range.

The input calibration would be something in the similar way, a simpel 
method would be to use a coax cable between output and input, and then 
use the internal output offset to measure the range of the input 
interpolator. However, the input interpolator is a decade better than 
the output interpolator. However, considering that I have a 5359A just 
waiting to be used, I think I use a fixed output PPS delay and trigger 
the 5359A with and then sweep that one.

I would then use the collected data to find suitable correction values.

Comments and suggestions? Experience?

Cheers,
Magnus
