UNIT

UNIT value The context UNIT will tel some other commands (mostly POINT) to choose the unit used. UNIT can take the values INDEX (number of channel) HERTZ (based on SPECW and OFFSET), PPM (HERTZ divided by FREQ) and SECOND (usefull only for FID). All other values are invalid.

UNREF

When this command is issued, the command line will not refresh the current display. Typically used at the end of a command line in macr : read file unref ; read the file but does not display it This is the inverse of REF

upzoom

upzoom permits to propagate a zoom window to a higher dimension Normally, each dim buffer (i.e. 1D, 2D 3D) have a independent zoom definition. however, commands like ROW, COL, PROJ (2D->1D) PLANE, PROJ (3D->2D) VERT (3D->1D) etc... copy the zoom definition from the higher dimension to the lower one. upzoom realizes exactly the opposite. if you are in nD, upzoom will copy the current zoom definition to (n+1)D using the last commands to guess the axis.

USWA

USWA {Fx} Take a complex data set in internal representation ( i.e. odd points real and even points imaginary), and put the real part on the left side, and the imaginary part on the right side of the data set. This is the opposite of SWA.
