Increases the resolution (reduces the spacing) between samples of data in either time or frequency domain data.
Linear interpolation is used between adjacent samples to create new samples evenly spaced between the original samples
Each time this command is executed, the Block Size (number of samples) in a Data Block is doubled
FRF-based curve fitting can be improved by increasing the number of samples surrounding each resonance peak
After the resolution is increased, a dialog box is opened showing the new Data Block resolution.
