External RF filters for Signal Analysis to avoid Overmodulation Effects

Narda ida2 filter30 March 2017 – Narda Safety Test Solutions released a new external RF filters for its IDA 2 handheld signal analyzer. These optional RF filters help users to in particular avoid out of band overmodulation without reducing the necessary measurement sensitivity when making measurements with the IDA 2 in highly dynamic measurement environments. These overmodulation effects can occur when very weak RF signals need to be measured in the presence of much stronger signals.

This is because high measurement sensitivity is needed for precise measurement of the relevant low strength signal. This can lead to overmodulation of the analyzer as a result of the comparatively high strength of signals in neighboring bands. In such situations, the new RF filters ensure that measurement sensitivity is maintained within a selected bandwidth. Various filters for different frequency ranges are available, from broadcasting to air traffic control and on up to the mobile telecommunications range. Each RF filter can be easily attached to the Interference and Direction Analyzer IDA 2 with a separate RF cable and Velcro adhesive tape.

Particular attention was paid when designing the overall filter dimensions to ensuring an ideal balance between the necessary frequency ranges and the required steepness of the filter on the one hand and small size, acceptable weight and, not least, optimum costs to the user on the other hand.

The N connectors used on the RF filters mean that they can also be used with the Narda Rack Mount Analyzer NRA and many other signal and spectrum analyzers as well as for laboratory applications in addition to the IDA 2.
