That is a good question.
The similar 100 MHz 2247A specifications divide the total bandwidth
into two frequency ranges at 25 MHz and say that peak voltage
measurements above 25 MHz follow the trigger response curve.
The 2445B/2455B/2465B/2467B specifications mention a 10ns minimum
pulse with *and* a maximum sine wave frequency of 1 MHz.
Maybe those two oscilloscope designs are too different to compare.

Looking for confirmation of my understanding of the Tek specs for
automatic voltage measurement in the 2400 series scopes.
Am I right in understanding that automatic voltage measurement is
spec'ed to 1MHz? And that it is not spec'ed to function accurately above
1MHz?
That's what I get from my reading of the the catalog pages and the
service manual. Am I reading those documents correctly?
Thanks.
