Test sequence example

This example uses the HP 54654A Operator’s Training Kit. A test sequence

is set up to test various signals on the board. This includes testing two

signals and conditionally performing one adjustment. First, the example test

sequence tests whether the master clock has the correct amplitude and

frequency. If the master clock fails the test, an adjustment should be

performed. If the adjustment cannot be made, the board is declared a failure.

Finally, the example tests the overshoot of an output signal on the board.

The test sequence is shown in the following flow chart.
