The reference is found in the text at
the beginning of the section. Your assumption is not correct because the
specification says the measurements of compliant PHY's are made at the
compliance points. Third paragraph of the section where the table is found:
"This standard defines the electrical
requirements of the signal at the compliance points IT, IR, CT, and CR
in
a TxRx connection. Each compliant phy
shall be compatible with these electrical requirements to allow
interoperability within a SAS environment."
I believe the specification is clear
on this issue.

Transmitter Device Source Termination
Hi all,
I was looking at the SAS 2 draft Table 44
page 153 and SAS 1.1 Table 43 page 149. In both drafts note b for
the measurements requirements says the following:
“All transmitter device termination measurements
are made through mated connector pairs”
This does not make any reference to the IT
compliance point, which makes me believe that it can be done with any connector
type as long as they are mated, for example SMA mated pair. Is that
assumption correct? If not, I think we need to clarify it more in the standard.
