Preamplifiers provide gain close to the experimental detector, before the signal-to-noise ratio is permanently degraded by cable capacitance and pickup. The SR550 minimizes noise and pickup in the connecting lines and reduces measurement time in noise-limited experiments. Power and control signals are brought from the lock-in by a 9-pin cable. The SR550 may also be operated independently by applying appropriate biasing (±20 VDC, +5 VDC).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3.6 nV\/√Hz Input Noise\u003c\/li\u003e\n\u003cli\u003eFET Input, 100 MΩ Input Impedance\u003c\/li\u003e\n\u003cli\u003eGain of 1, 2, 5 or 10\u003c\/li\u003e\n\u003cli\u003eSingle-ended and Differential Inputs\u003c\/li\u003e\n\u003cli\u003eAC Coupled Input\u003c\/li\u003e\n\u003cli\u003ePowered by SRS Lock-in Amplifiers\u003c\/li\u003e\n\u003cli\u003eHigh Common Mode Rejection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePlease see Datasheet for complete details and specifications.\u003c\/p\u003e","brand":"Stanford Research","offers":[{"title":"S.R.S.
