Particularly suitable for use with microsecond counters in experiments for determining speed of sound, including 12 V AC plug-in power supply. Both channels can be individually switched between the perating modes, “Signal” for connecting an oscilloscope, “Level” for connecting a voltmeters and “Pulse” for connecting a microsecond counter. The trigger threshold for the pulse depends on the gain of the pre-amp, which is adjustable.\u003cbr\u003eBand width: 10 Hz to 42 kHz\u003cbr\u003e\nGain: 20 to 70x\u003cbr\u003e\nOutput impedance: 1 kΩ\u003cbr\u003e\nOutput signal: Switchable between Signal, Level and Pulse\u003cbr\u003e\nSignal: 0 – 14 Vpp\u003cbr\u003e\nLevel: 0 – 7 V DC\u003cbr\u003e\nPulse: Low: 0 V, high: 8 V DC, length: 150 ms\u003cbr\u003e\nInputs: 3.5 mm jack plugs\u003cbr\u003e\nOutputs: BNC socket\u003cbr\u003e\nPower supply: Via 12 V AC, 500 mA plug-in power supply\u003cbr\u003e\nDimensions: 100 x 75 x 35 mm\u003cbr\u003e\nWeight, including power supply: 450 g approx. 9.6 x 6.3 x 3.1 in  \u003cli\u003e\n\t\tSecure online payment with SSL\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tExpert advice\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tFinancing available\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tEasy returns \u0026amp; exchanges\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tInternational shipping available\u003c\/li\u003e\u003ch5\u003e\u003cspan\u003eSpecifications\u003c\/span\u003e\u003c\/h5\u003e\u003cul\u003e\n\u003cli\u003eUPC: Not Specified\u003c\/li\u003e\n\u003cli\u003eGTIN\/ITF Barcode: Not Specified\u003c\/li\u003e\n\u003cli\u003eUnits of Measure: Not Specified\u003c\/li\u003e\n\u003cli\u003eOverall Product Length: Not Specified in\u003c\/li\u003e\n\u003cli\u003eOverall Product Width: Not Specified in\u003c\/li\u003e\n\u003cli\u003eOverall Product Height: Not Specified in\u003c\/li\u003e\n\u003cli\u003eWeight Capacity: Not Specified lbs\u003c\/li\u003e\n\u003cli\u003eActual Product Weight: 1.01\u003c\/li\u003e\n\u003cli\u003eProduct Assembly: Not Specified\u003c\/li\u003e\n\u003cli\u003eProduct Installation: Not Specified\u003c\/li\u003e\n\u003cli\u003eCountry of Origin: Not Specified\u003c\/li\u003e\n\u003cli\u003eCase QTY: Not Specified\/case\u003c\/li\u003e\n\u003cli\u003eCase Weight: Not Specified\u003c\/li\u003e\n\u003cli\u003eShips Via Freight: Not Specified\u003c\/li\u003e\n\u003cli\u003eProposition 65 Warning: Not Specified\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3B Scientific","offers":[{"title":"Default Title","offer_id":48199015137472,"sku":"1014521","price":352.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1403\/8729\/files\/1776973167563.jpg?v=1776973171","url":"https:\/\/tensnet.com\/products\/microphone-box-115-v-50-60-hz","provider":"TENSnet","version":"1.0","type":"link"}
