I ran the additional tests recommended by Poul and Magnus and I concur that the interpolator board is not the likely culprit. I reversed the input cables as well as the pods in separate experiments to rule out those contributors with no different results. I thought it may be a trigger circuit error so I fed the inputs with a locked TTL signal rather than a sine wave using Manual Trigger with no difference. It seems to be a coarse count error so I'll investigate the start/stop logic chain.
