Re: [BP] Interference tolerance test channels

[Joe M Abler <abler@xxxxxxxxxx>]

The new channel appears to be inline with what we stated - a tilt of the line from DC to about a 3dB drop at 5GHz.  Why do you feel the lower frequencies need to stay fixed?


Thanks,        Joe

Hi Charles,
DC and low freq's went down way to much! Can you create a model with the
same losses at say 1GHz or so and 2 dB less at 5GHz? I thought that's
what we agreed.

guys,

     I propose that we use the model ITTC_23.s4p for reduced attenuation
EIT modeling.  If it really will not work, ITTC_20.s4p is available as a
bail out channel.  If it looks too easy, let me know and i will step it 
up just
a tad.

     The numbers refer to the fitted attenuation at 5.15...GHz.
