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:
âAll transmitter device termination measurements are made through mated
connector pairsâ
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.
Thanks
Ramez
