I knocked up a quick and dirty Windows App to show how I think your generator operates.

I've uploaded it to youtube here:

B&K Signal Generator Level Control - YouTube

If the link above doesn't work then search for:

B&K signal generator

on youtube to find it under my username of G0HZU

Note that S9 on a signal meter on the HF bands is -73dBm which is 50uV rms into a 50 Ohm load.

A lot of signal generators display the voltage level in EMF and S9 is 100uV EMF and also a lot of service manuals quote S9 as 100uV. But this is 100uV EMF and

your sig gen is calibrated in Vrms into a 50 Ohm load.

So you need to select 50uV for S9 (-73dBm) and you can get this with the attenuation set to 66dB with the meter cal set to 0dB with the fine attenuator

Hope this helps
