Sciospec Multiplexers

functional multiplexing with endless possibilities

Ranging from 32 to 256 and more channels these multiplexers are the perfect choice for impedance measurements in any sequential multichannel setup. With constraint free any-to-any port assignments you can configure any 2, 3 or 4 port combination you need. The innovative SC98 connection standard gives you full flexibility for connecting to your application.

“These multiplexers are the perfect fit for high quality impedance

measurements.”

Scaling up channel count has never been easier. Just connect the multiplexer externally to any of our instruments with and ExtensionPort or have it fully integrated with the instrument. For applications that require multiple ports, electrodes, sensors, etc. but don´t need parallel readout our multiplexers are the perfect fit.

Any to any port assignments - nothing is impossible!

Did you ever find yourself in a situation where you had to solve the puzzle of assigning your sensor ports to a multichannel device but kept running into constraints? Maybe you even resolved to manually reconfiguring cables in between measurements to cope with this? Good news: These times are over! Freeing you of all channel assignment constraints as seen in conventional multiplexer arrangements, our any-to-any multiplexers give you complete freedom and take out the hassle and riddling of the port assignment and configuration process. Assigning ports becomes a breeze! Additionally, this opens up a world of new possibilities: switching polarities on ports, moving current paths on fixed sensing positions, fixed excitation points and scanned potential or impedance mapping, multiport component analysis, or anything else you can imagine. These multiplexers can do it. EIT style injection patterns are just as easily realized and combined with the EIT measurement option in our impedance analyzers you can do image reconstruction on top of your data.

With the ExtensionPort system the multiplexers just plug into compatible impedance analyzers like the ISX-3 and you´re good to go - it´s that simple.

Flexible connectivity through our SC98 connector standard

Connecting multichannel setups and sensors to measurement equipment can be a challenge. Of course, you can just get one of our breakout cables that gives you one coaxial connection line (e.g. MCX) per port on the multiplexer. But oftentimes this results in cumbersome handling and the application calls for a more sophisticated solution. That´s why we designed our SC98 standard with ease of use and design freedom at the core. The SC98 edge card based connection standard is easy to use, enables cost optimized customization and allows for highly flexible connectivity options.

Want to connect to a specific cable or connector standard? We build our cable adapters based on SC98 and so can you. Either choose from our range of standard connectors or build your own. We make the design data available to your team or build a custom design for you.
For those of your working with multichannel sensors – you can connect a PCB based sensor carrier directly to SC98. We have example layouts and test sensors available to get you started if you want to design you own or you can simply get one of our carriers and design your sensor into it.
More demanding requirements? Not a problem for our SC98 standard. For example, check out our MEArack building on SC98 to connect to a MUX64 or CSX-64.
We have SC98 to SC98 cables allowing you to very simply extend the connection path between the multiplexer and your sensor or adapter.
Want to add AC coupling or other filtering/protection networks to your setup? Nothing easier than that with SC98.

Superior switching characteristics

High isolation, ultra-low parasitic switches with superior performance compared to conventional semiconductor switches or mechanical relays

>10 TΩ || 0.4 pF isolation at power off or software selected cell disconnect
extremely low parasitic capacitance < 0.7 pF offers close to no cell loading
max. series resistance 200 mΩ in connected state
zero leakage current in on state
zero charge injection, no distortion, no noise contributions beyond thermal noise

ExtensionPort System

For flexible extension of its application possibilities application specific frontends and adapters can be connected to many of our instruments through the ExtensionPort system. Interface and specifications for the ExtensionPort are fully user accessible dramatically simplifying customer`s developments for and with systems like the ISX-3, ISX-3mini or ISX-5. The connector carries measurement signals for 2,3 and 4-electrode configuration, supply rails and digital IOs, which can optionally be configured as serial interfaces (I2C, UART).
