AWR1243: RX Gain Temp LUT

Dominic Wu

Part Number: AWR1243

If all the RX channels are enabled via the rlSetChannelConfig() API, the LUT return by the rlRxGainTempLutGet API will be the following very consistently

000A 000A 000A 000A 000A 000A 000A 000A 000A 000A 000A 000A 000A 000A 000A 000A 000A 000A 000A

However, with all the RX channels disabled via the rlSetChannelConfig() API, the LUT will be the following and will change subtly from time to time.

002C 002C 002C 002D 000B 000C 000C 000C 000D 000D 000D 000D 000E 000E 000E 000E 000F 000F 000F

It seems the logic is reverse, thoughts?

Hi Dominic,

This behavior is not expected - normally the LUT values that you see will be similar to your second set.

For the first read back of the LUT, at which point in the configuration sequence are you reading the LUT back? Note that the LUT may change after a profile config setting.

Best Regards,
Anand

I am reading the LUT after the profile configuration. This is the sequence of command I am sending.

Hi Dominic,

We are not able to replicate this behavior. Would you mind sharing a source file that programs your settings? We can see if we can replicate the issue using your settings.

Also, could you please confirm the DFP version that you are using?

Thanks,
Anand
