Keysight Technologies M9703B AXIe high-speed digitiser/wideband digital receiver upgrade

Keysight Technologies has introduced multimodule synchronisation for its M9703B AXIe high-speed digitiser/wideband digital receiver, which increases the total number of streaming and recording channels available with the device.

The new bundles options (-CB1/-CB2) enable multichannel phase coherent digital down conversion (DDC), which has applications in 5G, radar and satellite communications, as well as aerospace and defence. In dense urban RF environments where an interoperability and compatibility challenge may exist, the functionality of the -CB1 and -CB2 options allows users to capture and record a long duration of large frequency bands on multiple phase coherent channels.

It also allows users to quickly characterise the channel behaviour in these frequency bands and enables researchers to develop the necessary channel models for designing and validating air-interface alternatives.

With up to 320 MHz instantaneous bandwidth (IBW) with tunable intermediate frequency, the high-speed digitiser meets the needs for new technology development in 5G wireless mobile broadband. Used with the recommended host computer configuration, the new options allow guaranteed recording time, storing all I/Q samples for later analysis. A command line software application is included for a simple launch and control of the streaming and recording.

For other applications where gapless streaming and recording is not required, but there is a need to simultaneously read while acquiring, the new signal processing firmware (-TSR option) enables simultaneous capture and transfer of triggered acquisition data to the host computer.
