2mVx

2mVx is not a term with a single standard definition; it typically indicates the product of a fixed voltage increment, 2 millivolts, and a variable x. In mathematical notation, it can be read as (2 mV)·x, and its meaning depends on the context and the units assigned to x. When x is dimensionless, 2mVx denotes a voltage that scales linearly with x, with a nominal step size of 2 millivolts per unit of x. In electronics and signal processing, such a form is often used to describe simplified transfer relationships, calibration curves, or the output of a digital-to-analog converter with a fixed least-significant-step of 2 mV per count.

If x carries units, 2 mVx provides a scaled quantity that combines those units with a millivolt factor, so the resulting units reflect the product. For example, if x is a dimensionless code, V_out = 0.002 V × x yields a voltage. If x has units of volts, the expression would have units of volt-squared, which is typically not desired, signaling a need to reassess the model.

In practical usage, 2mVx appears in equations and datasets where a linear, unit-consistent scaling is convenient. It can serve as a compact representation of a gain-limited, linear response or a simple calibration term.
