ATV COMTECH RX AGC PLOT AGAINST LEVEL
- dbm.................AGC Volts
- -120..................1.32
- -110..................1.34
- -100..................1.36
- -90....................1.45
- -80....................1.65
- -70....................1.92
- -60....................3.66
- -50....................3.82
- -40....................4.15
- -30....................4.23
- -20....................4.23
- -10....................4.3
- 0.......................4.3
Note this AGC voltage was tested into
an high impedance and should not be loaded and you need to get
rid of the lower offset of 1.3Volts this was done in my case with
the A/D circuit.
These tests was carried out at 1271MHz
