Tool/software:
Good morning,
I have a problem with the internal non uniform DTGC of AFE5832LP. I'm testing some ramp / slopes using internal non uniform DTGC, for example : MAX_GAIN -> ZERO GAIN; ZERO_GAIN -> MAX GAIN; ZERO_GAIN -> MAX_GAIN -> ZERO_GAIN etc.
All seems to work fairly well, except that the gain seems to never go down the START_GAIN set. For example, in configuration MAX_GAIN -> ZERO_GAIN the noise image will appear flat at the maximum gain (but the memory provided show all the points as "negative" gain decrease). But If I do a ZERO_GAIN -> MAX_GAIN -> ZERO_GAIN configuration or a ZERO_GAIN->MAX_GAIN it appears correct.
If needed I can add the register write dump related the AFE configuration in these multiple configurations.
Best regards,
Mattia
