In the next lesson, we're going to look at
how you can change your power supply's output over time automatically.
A lot of people, I've found, don't know this.
If you use this in your testing, you can impress all your neighboring engineers.
Power supplies don't just have to output one power for a long amount of time.
You can go in and change over time what power output it has.
I think it's called output lists?
Can you speak about output lists a little more for power supplies?
List mode, for short.
It's a good way to change voltages.
You can either have it have a constant dwell time,
so it just steps through a series of voltages, each with the same amount of time
or it can set the list, each step to have its own independent time.
Some examples of doing that are, just recently,
we wanted to test a device to make sure it turned off.
If it was below a certain voltage,
we wanted the device to turn off so it wouldn't run down the battery.
List mode was a great way to do that.
We could test it at several voltages, ramping down,
and then see when the device turned off and verify the turn-off circuit.
