RF test equipment
Based on the I/Q analyzer function data, this device generates high-resolution spectrograms, persistence spectrums and time domain displays that were previously only available from expensive laboratory instruments. Radio spectrum interference and impairments can thus be detected and analyzed on the spot. Unintentional or deliberate RF interference, illegal transmitters or interference between permitted radio signals can be difficult to detect if it only occurs sporadically or is hidden under conventional signals. Narda Safety Test Solutions has equipped the new IDA 2 with I/Q analysis functions to also detect and locate such signals. The instrument records the I/Q data in real time at a maximum channel bandwidth of 32MHz, and saves up to 250,000 I/Q data pairs without compression, i.e. without loss of data. Based on this data, the IDA 2 computes high-resolution spectrograms, persistence spectrums or oscilloscope-like displays versus time. Computation is done continuously during the measurement or subsequently from the stored data set. Since the underlying data remain unchanged in the device memory, display parameters such as the frequency or time resolution afterwards can be altered, and the user can zoom in on details down to the original resolution offered by the I/Q data.
