This is the basic mode of operation for the 

D

ETECT

IV unit.  In this mode all four detectors 

are active at the same time. Each detector is designed to detect a specific type of target and is 
represented with a vertical bar graph which increases or decreases in height in relation to the  
detected signal(s).

The detectors are divided into 2 groups:  Transmitter detectors  and Device detectors 

Transmitter Detectors

On the left of the screen these detectors respond to active radio transmissions. 

 

Broadband CW  will respond to continuous transmissions both narrow band (e.g. analogue 

‘bug’) and broadband continuous transmissions (e.g. analogue video 
transmissions)

  Broadband Burst  will respond to intermittent or burst transmissions (e.g. digital mobile 

phones or frequency hopping devices)

 

  Note 

 Harmonic Receiver  will respond to continuous transmissions with better sensitivity than the 

Broadband detectors, the harmonic receiver will also have the ability to 
cancel out background signals and allow signals other than the strongest 
signal to be captured.
