The FOFFSET record can be used to offset the frequency that CCICAP reports in its tabular and plotted outputs. The frequency variable used in internal calculations is not affected by the .FOFFSET record. The .FOFFSET record can be used to increase the resolution of printed or plotted results. This feature is useful in studying narrow band circuits such as band pass filters and crystal oscillators where the analysis frequency is over a very narrow range and the variation of interest may not be sufficiently resolved in the standard output format. The .FOFFSET record has a single real parameter:
.FOFFSET F1
where F1 is a real number. F1 is subtracted from the internal frequency variable and the resulting offset frequency is displayed in tabular and plotted outputs.
