MIMO UWB Channel Sounder System with more than 100,000 measurements per second

The SH-42xx device family uses our innovative m-Sequence pseudo-noise design and provides an extremely high measurement rate – more than 100,000 measurements per second are possible. Developed for channel sounder measurements up to MIMO 5G, this system is suitable for many other applications that require high-speed MIMO UWB measurements.

 

The compact SH-4240 HS (m:mimo.hs) includes 1 UWB baseband transmitter and 2 UWB baseband receivers working in parallel. It optionally comes with a solid-state mass storage drive to capture measured data in real-time, e.g. more than 100,000 measurements per second. Thanks to our proven m:Sequence technology, it features excellent signal and timebase stability. The SH-4240 HSIQ (m:mimo.hsiq) version features an additional frequency conversion frontend for extended UWB bands with 1 ext. UWB transmitter and parallel high-speed I/Q reception (1 complex ext. UWB receiver built with both baseband receive channels).

 

The SH-4200M (m:mimo.base) works as a master and sync unit for m:mimo sensor networks and is needed if you intend on using more than one SH-4240 for your application. Therefore, the SH-4200M contains a master synchronisation unit with our innovative m-Sequence pseudo-noise design. It provides the RF master clock, DC power supply and digital measurement synchronisation for up to 8 distributed sensor nodes (type m:mimo.hs or m:mimo.hsiq) The m:mimo.base distributes the RF base clock and an UWB reference baseband signal for up to 8 m:mimo.hs/m:mimo.hsiq sensor nodes. It allows complete and stable RF synchronisation in a distributed MIMO network. In addition, it contains DC power supplies, a digital synchronisation interface and a LAN switch for up to 8 nodes. The PC for sensor network setup and control only needs to connect to the base unit and receives averaged non-real-time data from each node to allow the operator to check for correct functioning of the setup.
