SPFREQ, TBLNO, FREQ1, FREQ2, FREQ3, FREQ4, FREQ5, FREQ6, FREQ7
Defines the frequency points for the input spectrum tables SPVAL vs. SPFREQ for multi-point spectrum
analysis.
TBLNOInput table number. Up to 200 tables may be defined.
FREQ1, FREQ2, FREQ3,..., FREQ7Frequency points (Hz) for spectrum vs. frequency tables. FREQ1 should be greater than zero, and values must
be in ascending order.
The spectrum values are input with the SPVAL command. A separate SPFREQ command must be used for each table defined. Frequencies must be in ascending order.
Repeat SPFREQ command for additional frequency points. Values are added after the last nonzero frequency.
If all fields after SPFREQ are blank, all
input vs. frequency tables are erased. If TBLNO is the only non-blank field, all corresponding SPVAL curves are erased.
Use the SPTOPT and STAT commands to list current frequency points.
This command is also valid in PREP7.
