Pure signal optimal parameters

[Luca De Biase]

Hi all, 

Richie mw0lge, has written an interesting calculator of the optimal parameters for setting up anan sdr and samplers for best results with pure signal.

He has the parameters for anan radios but not for HL2.

Here the Richie's message:

7000/8000/G2's use 14dB pre-amps before the ADC, other Anan's use 20dB pre-amps. Ideally the input to the ADC should be around +3dBm. We aim for a 25dB step attenuator setpoint to minimise cross talk and to hopefully obtain a good clean puresignal sample to the ADC. The tool takes the pre-amp difference into consideration. I do not know the characteristics of the HL2 in this regard.

...

I ask, especially to Steve, if he can write here the same parameters but for HL2 so i can pass them for eventually add a correction to the calculator for the HL2 .
