Default Sensitivity gain by utilizing steady state polarization

Sensitivity gain by utilizing steady state polarization

What do we exactly mean by "utilizing steady state polarization" to gain sensitivity in an experiment?...I know that steady state should be achieved before the start of acquisition which means, in a way, it is already being used for 1H,13C/15N(isn't it?)...I am lost in understanding this concept!...also, how/why does it differ in standard pulse sequences and spin state selective coherence transfer experiments?

[U. of Ottawa NMR Facility Blog] Receiver Gain and Signal-to-Noise Ratio
Receiver Gain and Signal-to-Noise Ratio The signal-to-noise ratio in an NMR spectrum can be affected drastically the choice of the receiver gain setting, so care should be taken to set the receiver gain correctly for optimum results. At very low receiver gain settings, both the signal and the noise use only a fraction of the available digitization levels of the analog-to-digital concertor (ADC). As a result, the intensity of each point in the FID is represented with only a few possible values and the FID is "choppy". This is analogous to a black and white photograph being represented...
