Requires: Base Development System (Windows)

Right-click a digital bus glyph on the plot legend of a mixed signal or digital waveform graph and select Label Format»Configure Fixed Point to display this dialog box.

Use this dialog box to configure the encoding, range, and formatting of a fixed-point digital bus label.

This dialog box includes the following components:

  • Encoding—Specifies the binary encoding of a fixed-point number. Use the following components to specify the bit size to which you want the number to conform:
    • Signed—Specifies that the fixed-point data is signed. The sign bit is always the first bit in the bit string that represents the data.
    • Unsigned—Specifies that the fixed-point data is unsigned.
    • Word Length—Specifies the total number of bits in the bit string that LabVIEW uses to represent all possible values of the fixed-point data. LabVIEW accepts a maximum word length of 64 bits.
    • Integer Word Length—Specifies the number of bits in the bit string that LabVIEW uses to represent the integer portion of the value of the fixed-point data. The integer word length can be larger than the word length, and can be positive or negative.
  • Range—Displays the range and delta for a fixed-point number. Use the following components to specify the range of possible values to which you want the number to conform:
    • Minimum—Displays the minimum value for the fixed-point data range.
    • Maximum—Displays the maximum value for the fixed-point data range.
    • Delta—Displays the increment between numbers within the desired range.
  • Formatting—Specifies the format style and number of digits of precision for a fixed-point number. Use the following components to specify the format to which you want the number to conform:
    • Style—Specifies the formatting style of the fixed-point data. You can select from the following formatting styles:
      • Normal—Displays the fixed-point data in standard numeric notation.
      • Scientific—Displays the fixed-point data in scientific notation. For example, 60 in normal notation equals 6E+1 in scientific, where E represents the power of 10 exponent.
      • Engineering—Displays the fixed-point data in engineering notation, in which the exponent is always a multiple of three.
      • SI notation—Displays the fixed-point data in System International (SI) notation, in which the unit of measurement appears after the value. For example, 6000 in normal notation equals 6k in SI notation.
    • Digits of Precision—Specifies the number of digits after the decimal point.
