Forum Post: RE: TSW1400

Hi Matt, 

I tried running the tsw1400 and TSW3085EVM following slau374.pdf user guide ( section 3.5 )

Configured the DAC using the file DAC3482_1228p8MHz_2xInt_NCO_30MHz_single_sync_source_mode.txt as in document.

Selected WCDMA_TM1_complexIF30MHz_Fdata614.4MHz_1000.tsw in the TSW1400 GUI. I do see the FFT as expected.

Problem:

I see a -38dBm output on SA but occupied BW is only 65 KHz . This is a bell shaped output.

I don't get an expected result as shown in page 23 of slau374.pdf. 

Toggling the RF input LO ( 1780MHZ ) I see this signal toggling.

Am I missing anything ? 

Please advice

thanks

Venky
