Y ou'll find an Excel 97 file at the link located below this article. At the core of both alignments lies the weighted tracking error curve, which is essentially tracking error per unit of groove radius. This weighted curve places more emphasis on tracking error for inner grooves than for outer grooves, which is representative of the actual distortion caused by tracking error. Well, the easiest way to operate the spreadsheet is by using the Baerwald or L fgren calculator at the top of the spreadsheet page. The calculator has three yellow input cells and six green output cells.
Inputs are effective length, innermost groove, and outermost groove.
The output values change in accordance with the equations listed in the instruction area below the graph when new numbers are entered into any of the yellow input cells. The graph is a visual representation of the columns of numbers on the left, which are a function of three specific tonearm parameters, effective length, angular offset, and stylus overhang as displayed in the tan colored cells, A3, B3, and C3. These are also spreadsheet input cells, but initially they are linked to the corresponding calculator cells, I3, O3, and Q3 so the calculator controls the entire spreadsheet. However, the tan colored cells may easily be unlinked from the calculator simply by entering numbers into them. If this is done, the calculator operate autonomously from the rest of the spreadsheet.
