FUNCTION DESCRIPTION OF THE TRANSMITTER 

 

The NB.Z2000 is a DDS EXCITER with modulation AM, high power 100Watt carrier 
(400watt P.E.P.) and programmed to send out from 500KHz-2000Khz. 

It is equipped with all the protections that it needs, so that the unit never be risk 
from a wrong manipulation or from an unpredictable problem like the antenna, 
excessive temperature e.t.c 

The NB.Z2000 features high current returnable SWR (reflection) protection, 
protection for excessive output power and protection for excessive temperature of 
the amplifier. 

All the protections are accessible and their rates can be defined by the user. 

 

 

At the front side of the transmitter there is the screen, which 

portray the power of the transmitter and the reflections, the rate of the 
modulation and the amplifier’s temperature. The measurement of the watt meter 
is exact and the measurement shown to P.E.P. 

 

 

The NB.Z2000 dispose acoustic filter NRSC-1 10KHz and optionally 6KHz 
4KHz. 

     1OKHz  Test On Air                         

 

At the right side you can see the depiction of the headset range 10KHz to 
a receiver SDR.
