These new offerings address the growing need for better, faster measurements in the communications and aerospace/defense industries. The multi-module processing synchronization and optimized analog performance of the M9703A provide industry-best measurement accuracy for wide analysis bandwidth on up to 40 phase-coherent channels. The instrument’s deeper onboard memory allows extended signal acquisition.
Many multichannel applications such as radar, advanced MIMO or baseband-IQ (BBIQ), require excellent signal sensitivity and phase coherency across eight channels or more. Phase-coherent acquisition across multiple digitizers and optimized dynamic range is therefore required. Traditional test platforms are generally limited to a lower number of parallel phase-coherent channels, and the connection to the analysis software layer can be slow.
The Agilent M9703A wideband digital receiver/digitizer provides superior value in multichannel applications that need simultaneous wide-bandwidth and high dynamic-range measurements, such as radar emulation, test and calibration, or research and design validation in advanced MIMO and baseband-IQ applications.
The new M9703A-FRF option delivers industry-best dynamic range and sensitivity over the full input frequency range for improved analog performance, with optimized analog-to-digital conversion. This option offers improvements of 0.3 effective bits, 2dB signal-to-noise ratio, and 4dB spurious-free dynamic range.
The M9703A-LDC option enables fast and flexible measurements, with real-time digital downconversion (DDC) on the data for up to 80MHz analysis bandwidth (160MHz in I+jQ mode) with center frequencies from DC up to 2GHz. The wide input frequency range, combined with a very low noise power spectral density (down to -145dBm/Hz, which is comparable to a 16-bit digitizer), make the M9703A a step toward a fully digital receiver. In addition, the M9703A-LDC provides an accelerated connection to the software measurement layer, such as Agilent’s 89600 Vector Signal Analysis software.
The M9703A-M16 option provides 16GB of onboard memory, corresponding to 1G sample per second per channel, for applications requiring a long acquisition time.
The M9703A AXIe wideband digital receiver/digitizer, combined with an Agilent five-slot AXIe chassis, can reach up to 40 phase-coherent channels in only 4U of rack-mount space. This enables users to simultaneously acquire data on a large number of channels under dynamic conditions, reducing test and calibration time by days and even weeks.
