Measurement
The Set_fixture subprogram in lines 2390 to 2820, which configures the test fixture, is
described below.
Line 2440 Allows the user to return to the entry start line and re-enter the data if
an error (such as an invalid entry) occurs while entering the number
that identifies the test fixture.
Lines 2460 to 2560 Displays the list of supported test fixtures and prompts the user to
choose one of the items by typing in the appropriate number.
Line 2570 Converts the entered value into an integer and stores it into the Fixture
variable.
Line 2580 If Fixture is not an integer between 1 and 9, the program returns to the
entry start line.
Lines 2600 to 2810 Configures the test fixture based on Fixture. If Fixture is 9, which
means that the user opted to use a user-defined fixture, the subprogram
acquires the delay compensation value (electrical length) from the user
input and configures the test fixture accordingly.
For more information on the Inp_data subprogram (lines 2860 to 2970), refer to the
description in Example 4-1 on page 46.
