Narda expands IDA 2 features
Narda Safety Test Solutions has expanded the features of its Interference and Direction Analyser (IDA) 2 with 1μs time resolution to analyse frequency-hopping transmitters, the company announced on 1 July.
The expanded features allow the IDA 2 to analyse signal structures that could previously be analysed only through large-scale lab equipment. It can analyse interference and frequency-hopping hidden transmitters, and the signals can be subsequently localised.
The IDA 2 has a new high resolution spectrogram display mode that enables the type or 'fingerprint' of a signal to be identified. It writes spectrums line-by-line and highlights different levels by colour, enabling the user to quickly identify time and spectral relationships. This mode is based on the I/Q analyser operating mode.
A magnitude display mode in the IDA 2 shows the level characteristics versus time, enabling users to identify signals with time structures in order to set triggers and locate the sources.
The IDA 2 is tuned to a fixed frequency or channel to capture selectively and record digitised data. It can work at channel bandwidths of up to 32MHz. The hand-held analyser was developed for security and communication purposes. For security, it can be used to identify and locate transmitters.
