ZGA5920+amp Results from a simulator: Who knows what they mean?
Conventional LCR meters and impedance analyzers can’t measure what you need!
#
To correctly evaluate the characteristics of electronic components and circuits, it’s fundamental to make measurements in an actual operating environment.

Impedance Measurement of Electronic Components
Inductors and capacitor are used in large quantities in electronic equipment. To design high-performance equipment, it’s extremely important to accurately know the characteristics of electronic components used in equipment. LCR meters or impedance analyzers are generally used for measuring electronics components; however, measurable voltage and current are as small as a few volts and about several milliamperes. Some components are used under a voltage of 100 V or higher and current of 10 A or higher. The values measured by LCR meters and impedance analyzers may differ from those of actual operating conditions.
ZGA5920 provides measurements under actual operating conditions, with its
High-voltage input, Wide dynamic range, Isolation between inputs and outputs,
High-voltage, high-current power driver amplifier and Measurement adapter with a current detector circuit. In measuring and evaluating piezoelectric elements that are used as actuators, it really excels.

Measurement of Loop Gain of the Switching Regulator
To evaluate the stability of the circuit, loop gain is measured. ZGA5920:
Injects the signal into the loop, and measures the open loop gain under closed loop operating conditions.
Automatically calculates the phase margin and the gain margin that are used in quantitatively evaluating stability.
