captures and streams IQ data up to 54GHz, with 150MHz of real time analysis bandwidth, so well beyond the Ka-band. MS2090A and OmniSig AI is a value-add symbiosis for drone identifi cation, as well as for localising UAV remote controls; see Figure 2. Drone detection is not the unique
topic related to UAVs only. A&D companies engaged in drone design and manufacturing have other specifi c concerns that should be carefully addressed, in a timely manner and in sync with their product workfl ow. Reducing the radar cross section (RCS)
of the drone is a growing challenge, especially now that radar sensitivity is increasing exponentially and more electronics is being densely packed into ever smaller spaces. Regarding the Gigasample ADCs
and DACs that are at the foundation of the new digital transceiver age, Anritsu provides several innovative systems. Testing high-speed ADC requires two high-purity analogue signal sources, one for the signal input into the ADC and the other for the clock. Anritsu’s latest EcoSyn Lite modular signal source, along with the Rubidium benchtop signal generator, can be used to make high-speed ADC measurements. EcoSyn Lite is locked to 10MHz reference from Rubidium. T e RF output frequency and power of both EcoSyn Lite and Rubidium can be independently controlled during measurement. With EcoSyn Lite as clock source,
ADCs and DACs with sampling rates to 20GHz can easily be tested. Typical ADC measurements include ENOB, SFDR, SNR, SINAD and harmonic as well as intermodulation distortions. See Figure 3 for a proposed solution for testing high- speed ADCs. Both signal generators offer unveiled
phase noise performance (-140dBc/ Hz @ 10GHz output, 10kHz offset for Rubidium and -126dBc/Hz @ 10GHz output, 10kHz offset for EcoSyn Lite) that have the least impact on true ENOB, SFDR, SNR and other parameters of the ADC, thus rendering more accurate measurements.
