I am observing the transmitted signal in spectrum analyzer . I would like to know how to change the signal power .
Thanks & Regards
You can change the TX attenuation using the corresponding API function: ad9361_set_tx_attenuation (AD9361: sw/ad9361_api.c File Reference)
What environment are you running on the target no-os or Linux?
If you are using a pre-built image, with the IIO scope (on Windows or Linux),
FMComms2/3/4 Plugin Description [Analog Devices Wiki]
The transmit chain has an attenuation that you can control.
Hi rgetz ,
I am using no-os set up in windows .I am using HDL codes from this link https://github.com/analogdevicesinc/hdl/tree/hdl_2014_r2 and and software codes from https://github.com/analogdevicesinc/no-OS/tree/2014_R2/ad9361 link . I have ZC702 board and ad9364 . I am using the DMA mode to transmmit sine wave samples and observing them in rohde schwarz spectrum analyzer .I am able to see the spectrum of sine wave in spectrum analyzer , now I wanted to know how can I change the signal power from software setup and observe the changes in spectrum analyzer.
Thanks and Regards
