We are trying with the "Evaluation Board AD9910" with your software to make different types of frequency ramps.
For the ramp up everything works fine, but when we use the ramp down there is a problem.
The problem accurse when we use the "Ramp Down" for a bigger step then the previous "Ramp Up"
1st ramp: from 10 MHz to 30 MHz works ok
2nd ramp: from 30 MHz to 20 MHz works ok
3 ramp: from 20 MHz to 40 MHz works ok
4 ramp: from 40 MHz to 10 MHz error jumps immediately to 10 MHz
Our work parameters
Sample Rate = 1GHz
Ramp time = 2-3 sec
We need to be able to make different types of ramps with different gaps of frequencies independent from the previous ramp:
Load registers values, 1 ramp.
Load new registers values, 1 ramp etc
