Here are my results - this is for a D1000 Pro/CI with open phono inputs.
The phono stage settings are MC with max level 1.6 mV and high resistive loading, RIAA 1976.
(sorry for the over-sized images)
Apart from seeing some spikes at 50 Hz, 100 Hz and 200 Hz, presumably picking up some 50 Hz mains hum and harmonics thereof, the general shape of this looks similar to what @Confused posted. The levels are higher though: I guess this is largely because I have high resistive loading. The point being that with only 47 k-ohm across the input there is much more scope for noise pick-up than with the 30-ohm loading @Confused uses, which nearly short-circuits the input.
