The E4438C is a signal source, not a network analyzer.

Hope this helps: Agilent Technologies Creating and Downloading Waveform Files for N5182A, E4438C, and E8267D

There will be LO leakage at the carrier frequency, and depending on the power level, the LO leakage could cause distortion products between desired tones. You could place a tone at the carrier frequency.
