The CNG 70 USB is the smallest noise generator currently available on the market.
The range of frequencies, from 4 to 2,500 MHz, allows to carry out tests of passive networks in coaxial cable, even large.
You 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
characteristics of filters LTE.
The 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.
The calibration of FILTER and / or TRAPS.
To calibrate a channel filters or traps using CNG 70 USB generator is necessary to
connect the device under TEST in series with the RF cable and verify on the Spectrum of
the meter the correct response curve.
Use as REFLECTOMETER.
Combined with APP REFLECTOMETER available for ROVER HD Series meters, the
CNG 70 USB allows you to check the correct fit of a distribution network TV-SAT at 75
Ohm.
Through a T-connector, you can check the presence or absence of mismatch.
When the distribution will be perfectly paired the instruments show, in spectrum
mode, only the noise calibrated.
Conversely, 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.
The 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.
