Still no sign of it. Allegedly shipped on the 4th Dec., but the tracking number doesn't work. WTF? Will give it a few more days before I follow up.

Bier!! und Schnitzel!!!   :-+  JA!!!

Re the 50-Ohm termination and not being able to enable it... Isn't it a standard feature of the "A" model?
EV:
It is a little over 300 MHz measured with HP 8642A generator with BNC cable and 50 Ohm feed through terminator. Scope is DS2202 wiith HW1 and 300M option.

In the picture is sweep from 1 MHz to 350 MHz. Sweep time is 14 s, so one horisontal craticule division is 25 MHz. Cursor lines show the 3 dB levels.

EV:
It was about 240 MHz before updates.
NikWing:
what exactly are you doing?
I mean, what information could I gain from this? :)
