My Tektronix TDS-2002 digital oscilloscope has a feature that compensates for the unstable display when looking at phono cartridge signals. Firstly, it is important to use AC coupling instead of DC coupling. Secondly, you can engage the "sweep averaging" function to eliminate random noise. This will stabilize the display that would otherwise bounce around from record warps.

Here are some screen shots showing how stable the signals are when using the "sweep averaging" function. I was measuring azimuth.
