user text editor modify these SERINADE variables must adhere format shown above. variables described below: FilterFile: SERINADE filter specification file which also modified from within SERINADE design screen. PrinterId: printer number corresponding configured printer (see Appendix Printer Definition Table). example above, printer corresponds Postscript printer. PrinterPort: printer port address file name which graphics print will directed. Valid entries this field LPTn, COMn file name. file name entered, graphics screen written binary file which printed COPY file name LPT1: command. XScale: horizontal scaling factor which defaults value zero. When zero selected, auto-scaling performed SERINADE both horizontal vertical factors. Auto-scaling attempts provide scale factors such that apparent image seen display monitor reproduced printer. auto-scaled image acceptable your printer, this value adjusted. Scales specified percentage, with being scale 1:1, being 2:1, YScale: vertical scaling factor which defaults value zero. When zero selected, auto-scaling performed SERINADE both horizontal vertical factors. auto-scaled image acceptable your printer, this value adjusted. Scales specified percentage, with being scale 1:1, being 2:1, Landscape: Print frequency response portrait landscape (1); default zero. Note: auto-scaling does work properly when landscape mode selected; user must specify XScale YScale factors. IoMode: printer mode. following values valid: Printer output direct port hardware (default). Printer output BIOS (not recommended). Printer output stream (use this mode networked printers output directed file). PalletteInv: Invert color palette; most printers, print black lines white background, white lines back background. default zero. sense this reversed some printers. invert palette prior printing. Does affect screen display. Report File *.RPT file generates report filter design specifications documenting design. first three lines header information containing design dates software information. next seven lines define filter requirements. next three values define minimum clocking requirements HSP43124. These followed value each control register hexadecimal each control word sub-field broken decimal representation. hexadecimal values filter coefficients also listed. Signal Files Signal files used store real complex data interchange between SERINADE other signal analysis software. These data files conform file format used MONARCH Digital Signal Processing Software, consisting seven line header followed data itself. header section must follow this format: Line through Comments Line X-Axis Label Line Y-Axis Label Line Where letter real data complex data, number columns, number rows. Following header section, data arranged according specified number columns. Note: real imaginary parts complex number listed row, with real part first. frequency files H.FRQ, F.FRQ S.FRQ dimensional files Column frequency column magnitude response each respective stage. impulse response *.IMP dimensional file Column impulse response floating point representation created SERINADE. Imported file *.xxx created user using filter design software, filter which previously designed with SERINADE. This file format must onedimensional #taps) SERINADE signal file. coefficients should floating point format; coefficients must 1.0. number coefficients must from 256.
