E4422B

Hello,
 

I am using a E4422B ESG series signal generator. I am fairly new to this instrument, so please excuse my basic questions.

1. Is the modulation signal and the RF carrier derived from the same clock source? When I plot an RF carrier of say 100kHz and a modulation signal of 10kHz (via LFout ) on a scope, I can see a slow "walk" between the 2 signals which leads me to believe there is a small frequency offset. Is this typical? If so, could you tell me how I can get rid of this?

2. Can I derive both the RF carrier and the modulation from an external clock source?
