Does the Model 2015 have balanced inputs and outputs?
No, both the source circuitry and the measurement circuitry are a single-ended output and a single-ended input, respectively.
By treating the sine output and the inverted sine output as a single source, the combined source is a balanced output with similar impedances to ground. The source now is 8Vrms with output resistances of 100W and 1200W.
The user can create a balanced measurement input circuit by connecting identical resistances, such as 600W, to ground from each input terminal.
