I have the connection expert setup, and I can use the "N8241A Control Utility" to load a ".bin" file into the N8241A. For simplicity I did one of the example files that came with the software ( "200MHztone.bin") similar to the tutorial help with the "Control Utility Software". Then I have the WB I/Q setup on the 8267D, but when I look at the generated RF signal I get two frequencies around the carrier and I cant figure out why or how to fix it. I thought there was a filter at RF to reject the image frequencies. A screen capture is attached.
