Microtune RF TUNER MODULE query

Hi,

I’m doing some tests on the microtune 4937 DI5 RF TUNER MODULE (3x7702)
to
determine the modules gain sensitivity.

Essentially, i’d like to reproduce the IF AGC and RF AGC graphs, shown
in
the modules datasheet.

I intend on using the _set_rfagc and _set_ifagc methods in the
db_tv_rx.py
module to set the gain but am not able to determine the actual RF and IF
Levels from the amps on the module.

Does anyone know how I can access these values, from within the GNU
Radio
modules

Thanks,

Aadil
