Set Data Rate = 153. 6MHz, and DAC option to 2’s comp Set Data Rate = 153.6MHz, and DAC option to 2’s comp. In I/Q Multitone Generator, set the # to 1 and Tone center to 2MHz. Default samples should be 65536. Set the tone selection to “Complex”. Click on “Create Tones”. Click on “Send”. HSDC Pro GUI shall look as shown in following screen. The output will now be a tone at the NCO frequency, which is 30MHz.
