ADRV9002 and ZCU102 no-OS firmware

What PLL are you referencing?

Hi Travis,

I see that right now I am able to generate the signal at 2.45 GHz or so/  It is the same for booth channels. I am using this by choosing one CW tone from the console for either TX1 or TX2.

I need to change this 2.4 GHz signal to something lower . I presume  I am talking about the first LO ( PLL) that feeds the quadrature modulator for each channel.

Besides this, I see the signals represented correctly on my spectrum analyzer but al least the amplitude is not correct ( - 70 db or so) on the oscilloscope. Is this due the fact  that I need to load another profile ? It look's that the signal is in the RX bandwidth since  the  noise  bigger around 2.45 GHz for about +/- 1MHz.

I am using a loopback between TX1 and RX1A  . Same for channel 2..

Thank you for your reply,

Since you are in No-OS you need to implement configuration through the ADRV9002 API itself. See the API doc that is part of the SDK. If you want to control the LOs from IIO-Scope, you will need to use the Linux driver.

Hi Travis,

Thank you for your reply.

HI again Travis,

Even if it sound simple, I can not change the carrier frequency from no-OS firmware.

Can you tell me please how to do this >?

The no-OS firmware seems to be quite different compared with the LINUX driver.

Thank you,

See page 100 of of the userguide UG-1828.

Yes No-OS and Linux will be different. No-OS is for optimized designs where you want to minimize configuration paths. Linux has a system level that will maintain state for you.

Thank you Travis.

Everything works very well except the fact that on ADI Oscilloscope the amplitude is not correct. I mean it is very attenuated to abut  -70 dbfS. On my Tektronics Spectrum analyzer the amplitude corresponds to the value set in IIO. I will dig into the problem.

Thank you,

Cristian
