Other Parts Discussed in Thread: AFE7225

Hello!

In my laboratory i have TSW1400 , AFE 7225 EVM, TRF 370333EVM, TRF 371125 EVM and TSW3003EVM. Also i have oscilloscope.

In plans i'd like to send ipulses of different shapes from FPGA to TSW1400EVM and process them by equipment, listed below.

But yet i try to process the signal with TSW1400EVM and AFE7225EVM ( DAC interface) and to see output signal on the oscilloscope, but i have problems.

My question: can i realize the last experiment without any other equipment, and from what OUT on AFE7225EVM i should read the signal?

Thank you very much!

Hi Airat,

You should be able to view the output of AFE7225 on either SMA J5 (or IOUTA) or SMA J7 (or IOUTB) for channels 1 and 2 of the DAC respectively.

Please refer to section 2 of the document below on how to load custom patterns into HSDCPRO software.

I will also recommend that you start with a single tone to make sure your AFE7225EVM is set up correctly before loading your own custom file.

Thanks,

Eben

Hello, Eben!

I tried to view output of AFE7225 on either IOUTA and IOUTB by oscilloscope, but i've failed.

And i have a question about AFE7225 soft: when i try to download configurations on the EVM, i press " send all" or " read all", but it doesn't light up, what can cause such problem ?

I saw that document, but yet i have trubles with AFE7225, so i can't work further.

can you recomend smth for me?

Thanks a lot
