[PCR-1000] Noise Floor

[Eduardo Araujo]

Traugott
        I have measured many times the whole spectrum of different PCR1000
with a noise generator and if I recall correctly, there is gain jump from
8 to 15 Mhz from where, gain (or agc line) returns to normal.

  Another thing I've also noticed is that using a 10db pad ahead PCR1000,
this jump smooths considerably which made me conclude that an input filter
impedance mismatch is present.

  If you are interested in, I can bring tomorrow the images that shows the
phenomenon and send it to you.
