It decreases the effective DAC resolution, SNR, etc.\r\n\r\nThen it depends on what exactly you want to achieve.\r\n\r\nIf it's just for the test signals, then it's possible to generate test signals with digitally scaled amplitude via Setup/Tests. Level controls amplitude. Freq #1 and Freq #2 can be set to 0 to generate only one frequency.\r\n\r\nIf it's for the transmitted signals, then with Radio Model set to HPSDR the signal amplitude  can be digitally scaled with the Drive slider."}}
