All the "investigations" talked about in this thread should be applicable to the Lecroy models: WA102 WaveAce 1001 40MHz 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 |

@KeBeNe >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 |

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 |
