occheung 4b3f0c5612 4410-4412/RAM: replace screenshot with plot 2021-12-22 17:14:57 +08:00
occheung 1ce032605a 4410-4412/RAM: lower background frequency to 5MHz 
It is to make the plot easier for our eyes.

occheung d26fe0f5d5 4410-4412: configure_ram_mode add slack 
When the RAM data is larger, extra slack is needed to avoid underflow.

occheung 8f1a437378 4410: add ram modulation with synchronization example 2021-12-07 16:26:25 +08:00
occheung 011d63f3eb 4410: modify ram example 
* Use `prepare()` to init the arrays, would be great if the value can be prepared there. However, the type check was not happy about it.
* Separate RAM configuration into a separate function
* Separate DDS init, digital attenuation & switch config in an init function
* Use `dds.set()`. It is supposed to look simple.

All these are to avoid repeating the long code in the coming RAM+SYNC example.

occheung b657e0fea5 4410-4412: clarify nominal power 
The same figure can be found in sinara issue 354 / urukul issue 3, and it was meant to be an empirical limit for low frequency RF outputs.
