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).
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)
transmissions)
Broadband Burst will respond to intermittent or burst transmissions (e.g. digital mobile
phones or frequency hopping devices)
Note
because these two detectors are broadband in nature they only
indicate the strongest signal detected.
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.
