Web5. Peak to valley means the highest point of the signal to the lowest point. It's a little like peak-peak except that it implies a DC bias so that the "negative peaks" don't cross 0V, so valley is a better name for them. mm/µv means millimetres per microvolt, or metres per millivolt. What THAT means depends on context you haven't given us, but ...
