Hi All
I have ADRV9029/26 EVB depend on guide the power can be +_6dbm max how can i change the power output from TX port in 9026?Please
Best Regards

The full scale output power of the TRX is as below:
You can use Tx. attenuation control to change the Tx power.
BTW,Where from are you referring to +/-6dBm?
Dear Ramarao
Many thanks for your answer, but max what i can obtained of board -10 dbm whem i used the waveform or 2 tones abd ATT =0 for TX1.

At what frequency, are you measuring the output power? The EVB that you have is matched for Low band, Mid band or high band?
The output power also depends on the BB input waveform scaling that you are using.
For eg, if the PAR of the input waveform signal is 11dB and if you use -11dBFS scaling waveform, you could get an output power of 7(Max. power)-11 = -4dBm from the Tx.out.
Try testing with a CW tone initially.
Hi Ramarao
I tried to measure just one tone i got
after that i changed for my Signal which is
3.5Ghz,70Mhz bandwidth
I got this
Just to conformed
3.5Ghz,70Mhz bandwidth
70MHz? Are you referring to 5G NR or any other application?
5G NR does not have 70MHz as far as i know.
Also, the measurement bandwidth is per 100MHz where as it should be 70MHz as the channel BW is 70MHz. To me, it looks like you are getting the output power as expected.
Yes this for 5G NR,
I will repeat the experiment with100 MHZ .
