What do peak-to-valley and mm/µV mean

terminologyunits

I was reading a document where it says

Adjust the signal generator to apply a 1mV peak-to-valley input 6Hz
triangular signal at a gain of 0.001mm/µV.

What does peak-to-valley mean hear? Is it same as peak to peak?
And, what does mm/µV mean?

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 for example, mm may refer to the signal amplitude on the display of a REALLY SENSITIVE oscilloscope (or an oscilloscope driven from an amplifier).
