Atec Narda-IDA-3106 - Manual (Page 6)

Directional Antenna 1, ranging from 20 MHz to 250 MHz
ACTIVE DIRECTIONAL ANTENNA SET
Narda offers a set of three directional antenna modules covering the
frequency range from 20 MHz to 6 GHz. This addresses all major
applications for interference and direction finding.
The snap-in connector of the Active Antenna Handle picks up one of the
directional antenna modules aligned for either horizontally or vertically
polarized signals. IDA recognizes the type of antenna, alignment (H or
V) and corresponding antenna factors. Correction data based on the
frequency response calibration of the handle is automatically transferred
to the instrument. Inside the antenna handle a low noise, switchable
amplifier (0 dB/ 20 dB) provides very high sensitivity for weak signals.
Position sensors in combination with a 3D high resolution compass
accurately determine the current antenna orientation. This information is
automatically transferred to the IDA-3106 and assigned to the measured
RF signal.
Directional Antenna 2, ranging from 200 MHz to 500 MHz
Measurements from different locations are tracked by the IDA
embedded GPS receiver. Thus, triangulation can be performed
immediately and the results then be graphically displayed on the screen
of the IDA-3106. Triangulation becomes even more effective with the
Option Mapping, drawing bearing results and suspected emitter
positions directly onto a map.
IDA-3106 can also be used with antennas from other manufacturers,
e.g. for signal monitoring with omnidirectional antennas.
Directional Antenna 3, ranging from 400 MHz to 6 GHz
OTHER FUNCTIONS
Additional functions support practical applications during measurement,
analysis and evaluation. They make the IDA-3106 into a masterpiece for
interference finding, triangulation and localization:
Delta spectrum for easy detection of newly appeared emitters
(available in 2012)
High capacity time- or event-controlled data logger
Demodulation (via build in speaker or headphone)
