ETABLE TABLE (-15, -15), (15,15) EXPR V(%IN+, %IN-) GTABLE TABLE (-15, -15), (15,15) EXPR V(%IN+, %IN-) First, EXPR is evaluated, and that value is used to look up an entry in the table. EXPR is a function of the input (current or voltage) and follows the same rules as for VALUE expressions. The table consists of pairs of values, the first of which is an input, and the second of which is the corresponding output. Linear interpolation is performed between entries. For values of EXPR outside the table's range, the device's output is a constant with a value equal to the entry with the smallest (or largest) input. This characteristic can be used to impose an upper and lower limit on the output. An example of a table declaration (using the TABLE property) would be the following: TABLE = + (0, 0) (.02, 2.690E-03) (.04, 4.102E-03) (.06, 4.621E-03) + (.08, 4.460E-03) (.10, 3.860E-03) (.12, 3.079E-03) (.14, + 2.327E-03) + (.16, 1.726E-03) (.18, 1.308E-03) (.20, 1.042E-03) (.22, + 8.734E-04) + (.24, 7.544E-04) (.26, 6.566E-04) (.28, 5.718E-04) (.30, + 5.013E-04) + (.32, 4.464E-04) (.34, 4.053E-04) (.36, 3.781E-04) (.38, + 3.744E-04) + (.40, 4.127E-04) (.42, 5.053E-04) (.44, 6.380E-04) (.46, + 7.935E-04) + (.48, 1.139E-03) (.50, 2.605E-03) (.52, 8.259E-03) (.54, + 2.609E-02) + (.56, 7.418E-02) (.58, 1.895E-01) (.60, 4.426E-01)
