Hello.
After updating the DSO-X 2012A to the latest firmware, i found a rather curious problem, unsure if it's caused by the WFG, or by a lack of coffee on my side.
Connected the WFG-OUT to the CH1-IN using a 50Ohms cable, set the WFG to 1kHz square wave, Hi-Pot=1V, Lo-Pot=0V, Impedance=50Ohms.
On measuring the signal, the scope shows me a signal with 2Vpp, instead of the 1Vpp as expected.
Attached the display of the measured signal, with WFG settings still shown.
So the question arises, should i rather go to bed and call it a day, or is this supposed to be this way?

So its open circuit voltage is 2Vpp which is what you are seeing with CH1 set to 1Meg input impedance.
Set CH1-->Impedance-->50ohms.
Then it will show 1Vpp into the 50 ohm scope impedance.
