WaveAce 1002  60MHz
WaveAce 1012 100MHz
WA204
WaveAce 2014 100MHz
WaveAce 2024 200MHz
WaveAce 2034 300MHz
WaveAce 2004  70MHz
WA202
WaveAce 2012 100MHz
WaveAce 2022 200MHz
WaveAce 2032 300MHz
WaveAce 2002  70MHz

>Here is my measurement with 100mV, -3db point and 500Mhz.

Should be much more then -3dB from 300MHz to 500MHz.
(or did you other additional mods besides the cap removal?)

My scope (modified) have around 17dB att. from 300MHz to 500MHz.
The -3dB point is located around 325MHz.

The gen. provides 316mV/eff. Sig was splitted by a resistive  power
devider ( att > -6dB), so at scope input the amplidude @500MHz is:
316mV * sqrt(2) / 2 = 223mV (amplitude) and the scope shows 30mV
(amplitude) ==> 17,4dB attenuation. (a faktor of 7.4 concerning voltage
from sig to scope displayed)

Hopefully not making a mistake in my calculation ;-)

Markus,

Show us a freq. sweep of the new config.

 As requested,

the bw picture from 10MHz to 500MHz.
Zero line shifted down to get a better resolution.

Markus

PS.: Looking for marker hints. Perhaps a second channel
is uesfull to do this to mark the -3dB point.
KeBeNe:
here a sweep from 1 to 800Mhz from my scope
