Agilent claims breakthrough in phased-array antenna test
Agilent Technologies has introduced its widest-bandwidth real-time digital downconverter option on the M9703A AXIe eight-channel high-speed digitiser.
The digitiser has a frequency range of DC to 2GHz and a sampling rate of 1.6GS/s.
Most likely applictaions will include multi-antenna applications such as radar, direction-finding and satellite beam-forming, where phase-coherent acquisition channels are critical for accurate data acquisition, whether for antenna calibration or channel sounding.
“The M9703A high-speed digitiser with DDC functionality enables a breakthrough in phased-array antenna testing based on commercial off-the-shelf technology,” said David Myers, Agilent’s global business development manager for modular solutions.
“It enables customers in the defense and wireless industries to achieve the fastest possible flexible phase-coherent measurements, without compromising accuracy,” said Myers.
For complex signals, the real-time processing algorithm of the DDC functionality supports phase-coherent measurements across eight input channels.
The DDC programmable decimation ratio and fine IF tuning allow users to set the bandwidth and center frequency to match the analysed signal.
Real-time decimation allows users to analyse bandwidth from 300MHz down to less than 1kHz, reduces the noise level, improves the dynamic range by 3dB per decimation step, and extends the capture time.
The M9703A AXIe high-speed digitiser is compatible with Agilent’s 89600 Vector Signal Analysis software.
The digitiser, combined with an Agilent two-slot or five-slot AXIe chassis, allows users to scale up the number of parallel acquisition channels without the use of switches, reaching up to 40 channels in only 4U of rack-mount space using five digitisers.
The digitiser with the DDC option is also useful in electronic warfare and MIMO applications that need simultaneous wide-bandwidth and high dynamic-range measurements on multiple channels.
The M9703A-DDC and the M9703A eight-channel, 12-bit digitizer are available now. More information about product configurations is available at www.agilent.com/find/M9703A
