Be creative in looking for ways to test your design in stages rather than all at once. This reduces the chance of destroying components by large transient surges. Turn off signal power, then circuit power when you shut the circuit down. To prepare in a quantitative manner, you must have available the details that might limit your measurements. Perhaps the multimeter should be used to measure the amplitude instead of the oscilloscope.
Similar questions arise about the various signal sources.
Gathering this kind of information can be a cooperative venture. If you get done a little early, take down what you can from the various pieces of equipment. Integrated circuits require appropriate substrate connection to avoid destroying the chip. For one of our ICs, one manufacturer's data sheet shows the substrate grounded when it should actually be connected to the negative supply in a two-supply circuit.
