Radio Testbox Narrow Band
The Testbox includes a state-of-the-art narrow band radio receiver for detailed signal decoding and analysis. The activities in the channel ranging are made visible and audible by means of an LCD, LED's and a loudspeaker.
The Testbox gives an answer to the following questions:
- How reliable can a transmitted signal be received at a special location?
- How strong is the band used, and who uses the same band?
- What is the effective radiated power of my transmitter?
- Where should I install my receiver, in order not to be disturbed by other devices?
- Why is the operating distance of my recently installed radio-system suddenly bad?
- How does my modulated radio signal look like?
Features
- Customized software
(Various functions on your demand can be implemented)
- Detailed analysis
( Test points for the logarithmical field strength signal and the digital signal)
- It's simple to use !
(The testbox makes wireless visible and audible.)
