Description
Overview
The Ridley Engineering AP310 is a frequency response analyzer specifically designed for the power supply industry. It enables precise gain-phase measurements in high-noise environments, allowing engineers to measure transfer functions, loop gain, output impedance, and input impedance of power supply circuits and components.
Key Features
- Measures transfer functions, loop gain/phase, output impedance, audiosusceptibility (PSRR), and input impedance
- Advanced analog and digital signal processing for large and small signal measurements
- Built-in power amplifier with 20 V p-p at 2 ohms output
- 117 dB dynamic range for high-gain current-mode loop measurements
- Frequency range from 0.01 Hz to over 30 MHz with single wideband injection transformer
- Measures power capacitors, inductors, transformers, and leakage inductance
- Graphical variable output source control from 7 V rms down to 1 mV
- Direct measurement of analog signals up to 5V p-p without attenuation
- Isolated USB connection for enhanced noise immunity
- Integration with RidleyWorks design software for direct measurement comparison
Applications
- Power supply transfer function and loop stability analysis
- PFC circuit testing down to 0.01 Hz
- EMI filter and component analysis up to 30 MHz
- Power capacitor and magnetic component characterization
- Passive power component impedance testing
