[time-nuts] Symmetricom 58532A and 58536A group delay figures

[John Ackermann N8UR]

Found the data on the splitters: 
http://www.febo.com/pages/lab_documentation/gps_cable_delay/hp_gps_splitter/

My recollection was a bit off -- we saw about 22ns on the two-port 58535a and about 15ns on the 8-port 58517A.  I would guess the 4-port unit would be similar.

Unfortunately, I haven't been in a position to try to measure the delay through an antenna.
