LMX2492EVM: Ramp down and FSK

Part Number: LMX2492EVM

Tool/software:

Hi TI forum,

I'm new with this devices and I'm currently trying to configure the 'tutorials' inside User's Guide. When setting up FSK mode same way as UG and using a waveform generator with square waveform and 1 Vpp with a frequency of 20 kHz on MOD Test Point, and I can't recognise any difference in the output with the trigger on or off in Vtune test point. 

  (The difference you see at the corner is noise)

Also, when configuring trapezoid I found out it may have problems with ramp down because it can generate it

I tried a different test looking for ramp down I got the same, just a constant voltage and abrumpt jump in voltage

I can't find anything in the UG or my setup.

I can share more info if needed, such as pictures on how everything is connected.

Thanks in advance,

Joaquín.
