David,
It is just a coupler - nothing else makes sense for that use, so your
-60dB assumption is correct. Yes, it is relative to the output, so dBm
is not the proper designation.

I am trying to get ready for delivery of the KPA1500 and have become
confused about the information available for the TX Sample port.
The only information I can find states that this is a low-level signal
of -60dBm but dBm is a measure of absolute power which would put this
signal at 1 nanowatt.
My first thought is that this is a typo and meant to show that the
signal level on the port is -60dB with respect to output but need some
verification.
