For a project I am currently involved with, we are using TI AFE7920EVM board, and I have some questions about the startup procedure of the said eval module.
Currently we do not have access to any pattern & capture hardware, such as TI TSW14J56 module, nor is any kind of FPGA connected to the setup.
In fact, the environment where we intend to do our tests consist of the following equipment:
- RF signal generator (serving as a sine-wave source, where the sine-wave is at 2245 MHz, with power of -10 dBm)
- Spectrum analyzer (centered around 2245 MHz, with span of few GHz)
- External clock reference @ 10 MHz
- DC PSU with 2x 5.5V output
- 3x RF cables terminated with SMA connectors
- 1x USB cable
- AFE7920EVM
- PC with TI Latte software installed
The RF signal generator is supposed to be connected to one of the ADCs of AFE7920EVM (e.g. J3-RXA), while one of the DACs of AFE7920EVM (e.g. J9-TXA) should be connected to the spectrum analyzer.
External 10 MHz clock reference is connected to the J14 connector of the AFE board (LMK_CLK_IN).
AFE7920EVM is powered up from the PSU and it is connected to a PC with Latte software via USB cable.
TI Latte software is set to test the scenario from the Python script defined in configuration 5, which should correspond to the repeater configuration.
Since there is no pattern & capture hardware present, nor an FPGA is connected to the system, all of which are components present in the test setup in the available TI AFE79XXEVM documentation, we are currently not sure how to properly set up our system in the repeater configuration without pattern & capture hardware.
It is for this reason why I am reaching out, in hope that the it would possible to get some guidance in setting up our test environment properly.
Note that I already have access to the TI secure software website, but the User’s Guides and Software section there held little to no information relevant to my question.
