33210A What's the output noise level or SNR?

Hello All,

I'm trying to use the 33210A signal generator to determine SNR loss of an ADC with poor PCB layout. The ADC's SNR from datasheet is 85dB and my measurement shows 70dB. I need to determine how much from that 15dB difference is on the ADC side and how mych comes from the generator itself. In order to do that I obviously need to know what's the noise of the generated signal. I don't have access to any equipment to measure the generator's output signal noise or SNR. Is there any way to determine that from the information from the generator's datasheet? Signal that I'm using is 1.4V of 100Hz sinewave and my final measurement bandwidth is 6kHz.
