SS is signal strength. There is a setting somewhere buried deep in the SCPI to

I guessed SS probably was signal strength, but what values are good
and bad? There's nothing in any manual I can find that mentions SS on
the 58503A. I can't find any SCPI command that is supposed to switch
the display units.
The 58503 manual gives this detail:
C/N (58503B)
indicates the carrier-to-noise ratio of the received the signal, from a
range of 26 to 55. A ratio below 35 is a weak signal that may not be
acquired by the Receiver.
SS (59551A)
indicates the strength of the signal, from a range of 0 to 255. A signal
strength of 20 to 30 is a weak signal that may not be acquired by the
Receiver.
I suspect that the SS was upgraded to C/N in the development.
Cheers,
Magnus
