What is frequency scanner?
The scanning frequency is the period of time required for one full scan of a complete line when the measuring object is sequentially scanned using a laser beam.
Can you scan 800 MHz?
Scanning Tips for 800MHz. First off, you need to use a scanner with full 800 MHz coverage. Not only the full 800 MHz region itself, but the scanner must be capable of receiving the scanning steps peculiar to the 800 MHz region, such as 30 khz steps (scanning increments) or the 12.5 khz steps as well.
Do police use UHF or VHF?

Is NFM and FMN the same?
No – FM is a mode. NFM (and WFM) is exactly the same mode. The extra letter indicates the bandwidth in general terms. FM means absolutely nothing at all without the deviation, in the same way people mis-label AM.

How is RF signal detected?
The RF signal from 1 to 4.5 GHz can be detected by adjusting the frequency of relaxation oscillation which is related to the laser bias current. The system provides a maximum gain of 15 dB for the low-power RF signal. The sensitivity of the system can reach up to as high as -97 dBm.
What is a 800 MHz radio system?
An 800MHz radio system is a blend of traditional two-way radio technology and computer-controlled transmitters. The system’s main advantage is that radio transmitters can be shared among various departments on campus, with the aid of computer programming.
What frequencies can I use without a HAM license?
