ADRV9004 adi_adrv9001_Tx_Attenuation_Set function has no effect

Hi,

Which version of the SDK are you using? Can you try checking in the latest version of SDK27? Are you trying to read in C, Python, or Matlab? Are you able to use the ADRV9004 adi_adrv9001_Tx_Attenuation_Get API? What error are you encountering? 

Regards

Rahul 

Hi, RahulMushini  , my SDK version is below.
/* */
/* Silicon Revision: Presumed C0*/
/* */
/* Tx / Rx optimal carrier frequencies: 30 MHz to 6 GHz*/
/* External LO optimal frequencies: 60 MHz to 12 GHz*/
/* */
/* FPGA: v0.0.0*/
/* Device Driver API: v0.0.0*/
/* Device Driver Client: v68.0.6*/
/* Firmware: v0.21.0.9*/
/* Profile Generator: v0.51.3.0*/
/* Stream Generator Assembly: v0.7.9.0*/
/* Transceiver Evaluation Software: v0.22.0*/
/* ADRV9001 Plugin: v0.22.0*/

This version SDK works well with ADRV9002 on old board. But when i use it with ADRV9004 on the new borad, it has no effect.

THe output power is abut 6~7dBm at full scale.

Let's me try adi_adrv9001_Tx_Attenuation_Get() tomorrow.

adi_adrv9001_Tx_Attenuation_Get()  shows the config attenuation value. but it has no effect actually.

So you are able to inspect the attenuation value. Are the attenuation value assigned to the correct channel? Can you use the latest sdk and test it out.
