The SR860 front end offers both state-of-the art voltage and current input amplifiers. The voltage input is a switchable single-ended\/differential JFET-pair amplifier with 2.5 nV\/√Hz of noise at 1 kHz and under 10 nV\/√Hz of noise at 10 Hz. The voltage input has a 10 MΩ input impedance and can be AC or DC coupled. Input connector shields can be connected to the instrument ground through a user selectable 10 Ω (Ground) or 10 kΩ (Float) resistor. The SR860's built-in current amplifier represents a significant improvement over previous designs. The current input range is selectable from 1 µA or 10 nA. The 1 µA range has 400 kHz of bandwidth and 130 fA\/√Hz of noise, while the 10 nA range offers 2 kHz of bandwidth and 13 fA\/√Hz of noise.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\t\u003cul\u003e\n\t\t\u003cli\u003e1 mHz to 500 kHz frequency range\u003c\/li\u003e\n\t\t\u003cli\u003eTouchscreen data display\u003c\/li\u003e\n\t\t\u003cli\u003e1 µs to 30 ks time constants\u003c\/li\u003e\n\t\t\u003cli\u003eLow noise voltage \u0026amp; current inputs\u003c\/li\u003e\n\t\t\u003cli\u003eHigh bandwidth outputs\u003c\/li\u003e\n\t\t\u003cli\u003eHDMI video output\u003c\/li\u003e\n\t\t\u003cli\u003e10 MHz timebase input \u0026amp; output\u003c\/li\u003e\n\t\t\u003cli\u003eGPIB, RS-232, Ethernet \u0026amp; USB interfaces\u003c\/li\u003e\n\t\u003c\/ul\u003e\n\u003cp\u003ePlease see Datasheet for complete details and specifications.\u003c\/p\u003e","brand":"Stanford Research","offers":[{"title":"Default Title","offer_id":52537720242519,"sku":"SRSSR860","price":1.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/9389\/0135\/files\/SRSSR860.jpg?v=1768380422","url":"https:\/\/www.tsdwelltest.com\/products\/stanford-research-sr860","provider":"TSD Welltest Solution","version":"1.0","type":"link"}
