dealing with vibration noise in encoder readings

Python 3.9

CRIO 9053

9411 module

Automation Direct/koyo trd-n5000-rzwd encoder (5000 pulses per rotation, totem pole output)

192 mm circumference wheel

Now that I have the encoder readings working, I have hit my next problem.

The bit of code below reads things just fine, but when I slap the side of the encoder, I see a series of spikes that incorrectly lead the the conclusion that the encoder has moved backwards and then forward by 0.038 mm.  Looking at the trace, I can see why -- my scope skills are not that great, but I measure the spike at 7.8 ms.

This may just be no big deal, given that the error I see over 15 seconds of repeated vibration yielded total false movement of 0.038 mm, a value far below the precision I need -- but still, I want things to be tidy.

Is there a mechanism I am overlooking for dealing with this?  Just using the minimum pulse width does not seem to be the best way forward here.
