Stability — Gain / Phase (Bode Plot)

Measure your control loop’s gain and phase margin with a Bode plot — the clearest picture of how stable your power supply really is, and how much margin you have before it rings or oscillates.

Works with any VNA. Buy the parts you need below, or request a quote for the full setup.

What you need to make this measurement
VNAAny VNA — sweeps the loop and plots gain & phase
CoreJ2101A Injection Transformer — the most general-purpose injector; with a basic 10:1 probe this is all you need for a Bode plot
CorePML 111O Passive 10:1 Probe — recommended probe for clean Bode-plot measurements
OptionalJ2110A Solid-State Injector — for noisy supplies / high-ripple systems
OptionalB-AMP 12 Amplifier — adds injection drive on noisy supplies
OptionalJ2140A Attenuator — for voltage references, op-amps, or lower injection levels
