Using low-noise amplification unit, optimized low-noise power supply, etc., it boasts high precision, ultra-low noise, high suppression ratio, wide measurement range and low temperature drift. Thus, it can be widely used for weak signal measurement.\u003cbr\u003e\u003cbr\u003eThe preamplifier adopts all-metal shielding, and its internal core unit is shielded separately again to isolate the maximum scale of interference. Its power supply unit adopts a wide input range and high reliability design. It is moisture-proof and shockproof and can adapt to the application of strong industrial interference.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003cbr\u003e- High precision, low noise and small frequency response error\u003cbr\u003e- With precision devices, the preamplifier boasts high stability\u003cbr\u003e- Metal shielded shell with strong anti-interference ability\u003cbr\u003e- Adjustable gain and three switchable gains\u003cbr\u003e- With filtering and pass-through switching\u003cbr\u003e- Very wide voltage input range\u003cbr\u003e- BNC input and output for easy connection to various instruments\u003cbr\u003e\u003cbr\u003e\u003cb\u003eApplication:\u003c\/b\u003e\u003cbr\u003e- Very weak voltage signal amplification\u003cbr\u003e- Ultrasonic preamplifier\u003cbr\u003e- Photoelectric transmission preamplifier\u003cbr\u003e- High-performance pre-amplification\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x Preamplifier\u003cbr\u003e- 1 x Input lead\u003cbr\u003e- 1 x BNC output cable\u003cbr\u003e- 1 x Power adapter\u003cbr\u003e\u003cbr\u003e\u003cimg style=\"width: 1000px;\" src=\"https:\/\/www.byimg.com\/catalog\/84437\/84439-01.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"width: 1000px;\" src=\"https:\/\/www.byimg.com\/catalog\/84437\/84439-02.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"width: 1000px;\" src=\"https:\/\/www.byimg.com\/catalog\/84437\/84439-03.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"width: 1000px;\" src=\"https:\/\/www.byimg.com\/catalog\/84437\/84439-04.jpg\"\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAdjustable gain and total gain:\u003c\/b\u003e\u003cbr\u003e- The gain of the first stage of the amplifier is A1, the gain of the second stage is A2, and the total gain is Aout. Aout=Al*A2.\u003cbr\u003e- If you want to achieve the maximum signal-to-noise ratio, the first stage magnification should be as large as possible. The second stage cannot change the signal-to-noise ratio. Usually the noise and signal of the first stage should be amplified at the same time.\u003cbr\u003e\u003cbr\u003e\u003cimg style=\"width: 1000px;\" src=\"https:\/\/www.byimg.com\/catalog\/84437\/84439-05.jpg\"\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"VKinging","offers":[{"title":"Default Title","offer_id":40828617162801,"sku":"84439","price":222.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/7078621741105_watermarked_0.jpg_0.png?v=1767732037","url":"https:\/\/www.thanksbuyer.com\/de\/products\/vkinging-vk301-1hz-20khz-20-60db-low-noise-preamplifier-vk30x-series-low-noise-voltage-preamplifier","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
