Narda Safety Test Solutions has expanded the features of its Interference and Direction Analyzer (IDA), which will clarify and improve wireless signals. The IDA “Spectrograms with a time resolution of as fine as 1 μs now allow insights into signal structures that were otherwise only possible with large scale lab equipment. This means that interference and hidden transmitters with rapidly changing frequencies can also be analyzed and then localized with subsequent operating steps,” according to the company.
Narda recently introduced the IDA 2, which yielded the discovery of reveal hidden interference and transmitters that use frequency hopping.
“Because the available frequency spectrum is limited, many modern communications methods increasingly make use of frequency hopping (frequency hopping spread spectrum, FHSS): By changing frequency continuously, several devices can always find frequencies or channels that are unoccupied. Typical applications in the ISM frequency band include WLAN and Bluetooth, along with remote control for drones. Some GSM operating modes also use frequency hopping. Illegal transmitters make use of this method, too, hopping about to make themselves almost impossible to pinpoint. This type of interference can also occur unintentionally with transmitters operating legally,” Narda explains.
The IDA 2 offers a high resolution spectrogram display mode, and a magnitude display. The instrument can also set bandwidths up to 32 MHz, automatically compute position of interference, automatically recognize the antenna being used, automatically apply stored data and more. The device also includes an internal buffer battery and weighs less than 3 kilos.
