Above 20 MHz minimum signal in-
creases 40 dB/decade to =l V p-p.
Above approximately 80 MHz no
amount of input signal can cause
triggering.

below 100 MHz and ~ 1 2 Vpk-pk.
For 6 1 Vpk-pk signals; between
100 MHz and 350 MHz (CH A) or
300 MHz (CH B). There is no effect
if the slower signal has a square
edge or a slew rate

are commoned to the CH A bnc.

AC measurements near the slower
limit are not recommended, be-
cause they become duty cycle
dependent.
Frequency Upper frequency limit is
essentially a limit on thle
repetition rate at which riselfall
edges may occur.
Lower limit is a limit on the ability to
acquire peak voltage levels. Once
levels are set, riselfall will work
down to GO Hz.

50 Q input impedance is main-
tained via an internal power-
splitter causing X2 attenuation.
These specifications apply only
when both channels have the
same setup.
