Don
Was fairly certain that units were used incorrect but ya' never know so
appreciate confirmation.
Wanting to get linearity test ready so now I know what is needed to set
up. I always want to monitor a new amp and the inclusion of this output
allows that.
Now I do have one other "assumption" and that is the coupler is before
the internal ATU so it is always working with a 50 ohm load, hopefully
that is correct.

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.
