Looking at the 2nd photo it looks like you've set the output to approx 100uV, maybe a bit low for the 'scope, try turning the voltage output control to 10 and the multiplier switch to X10mV, if no go then it would suggest a poor connection or that the attenuator might be faulty, sometimes caused by a burn up or overload due to the output being connected to a high voltage/current source without using an isolating capacitor.

Remember that turning the voltage output control and the multiplier switch clockwise increases the output not the amount of attenuation.

From memory I think the RF plug is a standard 75 Ohm TV coax plug.
