Sweep Settings on CFG250

The documentation for the freq generator is very poor. Playing around with the settings, I came up with the follwoing remarks

• Sweep rate: sets the frequency at which it goes thorugh 1 complete "chirp"
• sweep width: sets the top frequency at which it sweeps.
• frequency: sets the bottom frequency

Tests

• FebTwentyThree
• FebTwentyFour
