Product code: CNG-70-USB.\u003c\/p\u003e\u003ch2\u003eProduct information\u003c\/h2\u003e\u003cp\u003eThe CNG 70 USB is the smallest noise generator currently available on the market.\u003cbr\u003eThe range of frequencies, from 4 to 2,500 MHz, allows to carry out tests of passive networks in coaxial cable, even large.\u003cbr\u003eYou can measure the C \/ N ratio, the measurement and analysis of amplifiers or CATV networks. Moreover, its use allows you to calibrate channel filters or check the\u003cbr\u003echaracteristics of filters LTE.\u003cbr\u003eThe CNG 70 USB can be used with any meter or spectrum analyzer, even from other brands, connected to an external USB power supply from 5V, or with batteries of the same voltage by connecting it to the USB output of a common Power Bank.\u003cbr\u003eThe calibration of FILTER and \/ or TRAPS.\u003cbr\u003eTo calibrate a channel filters or traps using CNG 70 USB generator is necessary to\u003cbr\u003econnect the device under TEST in series with the RF cable and verify on the Spectrum of\u003cbr\u003ethe meter the correct response curve.\u003cbr\u003eUse as REFLECTOMETER.\u003cbr\u003eCombined with APP REFLECTOMETER available for ROVER HD Series meters, the\u003cbr\u003eCNG 70 USB allows you to check the correct fit of a distribution network TV-SAT at 75\u003cbr\u003eOhm.\u003cbr\u003eThrough a T-connector, you can check the presence or absence of mismatch.\u003cbr\u003eWhen the distribution will be perfectly paired the instruments show, in spectrum\u003cbr\u003emode, only the noise calibrated.\u003cbr\u003eConversely, if there were a mismatch caused, for example by a cable in short circuit, broken or not properly terminated with a 75 Ohm load, on the spectrum of the Instrument will create a standing wave.\u003cbr\u003eThe navigation menu of the instrument, through the two markers, allows you to select the two null, obtaining at the bottom left of the display the exact distance of the interruption of the cable.\u003c\/p\u003e\n                ","brand":"Alltrade","offers":[{"title":"Default Title","offer_id":68237365641520,"sku":"CNG-70-USB_403A","price":343.2,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0689\/8162\/1040\/files\/cng-70-usb-img-1.jpg?v=1793621475","url":"https:\/\/freesatspares.co.uk\/products\/rover-usb-white-noise-generator-4-2500mhz-cng-70-usb","provider":"Freesat Spares","version":"1.0","type":"link"}
