This video shows you how to collect a family of Gain/Phase plots for a TI 5V 2.5A power supply, as the load current is varied from 2.5A to 1A and then 0.5A.
Family of Curves
You can use the 'AddRef' persistence command to make a family of curves, and then step around them, and make further measurements as needed.

Output Impedance
This video shows you how to connect up a CS328A-FRA and measure the Output impedance of an LTC3589 over the frequency range 20 Hz - 1 MHz. > Read more
BNC Fixture Calibration
In addition we can compensate for the open circuit capacitance of the fixture. This video shows you how to simply calibrate a fixture, and then shows you the results with three 0603 SMT capacitors.... > Read more
