TX attenuation table mapping

The Tx attenuation step Size is 0.05dB (50mdB). Unlike Rx path where the user provides Gain Index and there by the attenuation gets set, user would provide Tx attenuation and the respective gain index would be set which the user need not know. See below for understanding the Gain Index from the set Attenuation value. If the user sets 0dB, Gain index of 0 would be set.

in the table how did you compute analog value and digital value

Analog attenuation is calculated as below:

Digital attenuation is calculated as below:

LMK if you have any follow up questions.

so here analog attenuation value, typically ranges between 0 and 64 right?

Yes, thats correct.

like how can we get to know the ranges , if not mentioned in user guide

We will document them in the next release of UG. However, since this is something which in general is not changed by the user, we did not explicitly mentioned.

okay thanks for clearing all the doubts , its was very helpful
