Finally, NanoVNA Saver versions 2.2 and 4.0 were used with calibration done on NanoVNA itself. The offset delay was done in Saver. S11 phase was flat with - 14.56 nanoseconds required which is the one-way delay and negative in sign.
Summary - Offset delay was equivalent for all cases but required taking half the round trip delay and negating the sign for NanoVNA Saver. One wonders which one of these methods is used in commercial analyzers......
thanks for confirming
