Hello Mirek,
Thank you for the follow up.
Regarding the sweep time, I did forget that the SA44 and SA124 units do behave slightly differently. Unfortunately, the SA44/SA124 do not have a selectable sweep time, mainly because there are heavy restrictions on how the unit sweeps which limits us to very specific configurations for given RBWs and spans. These limitations are in hardware/firmware. Because of this, the sweep time parameter is ignored for these devices. Additionally the sweep time printout on the graticule is updated each time the screen is refreshed with new sweep data. So yes, as you mention, for the wide and long sweeps on the SA44/SA124 this number will not represent the total sweep time. Apologies for the confusion. For our BB60C and for narrower sweeps in the SA44/SA124, then the sweep is updated in its entirety each screen update and thus that number is more representative of the overall sweep time.
Regards,
Andrew
