NG-283德國Promax噪聲信號發生器的主要特點：
| NG-283 1 - 2200 MHz noise generator |
 |
The NG-283 is a handheld broadband white gaussian noise generator for testing coaxial networks, components and aligning coaxial cable at all frequencies between 1 and 2200 MHz.
Using a signal level meter or spectrum analyzer a frequency response of a coaxial section can be measured for TV?Terrestrial and Salite bands.
