DANL with and without optional Preamplifier

- I am using a RSA250X without preamplifier. Which DANL do I reach with and without preamplifier?
The typical DANL without preamplifier (Reflevel @ -38dBm) should be within -165dBm/Hz which is an excellent value.
With preamplifier you should reach a whopping -170dBm/Hz (Reflevel @ -60dBm) or even better.

How was this measurement done? With a zero span and 1Hz RBW?

The setting does not really matter:
Sweep and real-time mode both offer quite the same DANL same with the RBW setting.
