Tx running in Stream-Mode is allways "yellow" (USB Underflow)

I am generating a 16QAM signal with 2MHz sample rate with the IQ Signal generator but if i stream the signal to the Tx I get a warning (USB underflow) and the Tx shows up in yellow color (doeas not switch to green). What am I doing wrong?


You need to activate a slight streaming "buffer" by setting the Time Offset to at least -20ms:

Adjusting the Time Offset for Stream Mode


We might adjust those setting fully automatic within one of the next updates so you dont need to care about those setups any longer.

The Time Offset is now set fully automatic so there is no need any more to adjust it by hand.

it always be shown the warning(yellow Tx) after pushing on Tx on several seconds. and I had checked the Power cable. The warning is yellow Tx yet .

Follow the hints from the error message. You PC might not be powefull enough or your SSD is to slow (in this case the File Source should work since it loads the complete file into the much faster RAM).
