Solartron/Schlumberger 1253

The Solartron/Schlumberger 1253 is a dual-channel frequency response analyzer (FRA) that measures gain and phase characteristics across dynamic systems using Single Sine Correlation (SSC) technique. Engineered for production and maintenance testing, it delivers transfer function accuracy of ±1% in gain and ±1 degree in phase, making it suitable for servo systems, power supplies, modems, acoustic devices, and electromechanical components.
