the Medical Research ISX-3

You want to use impedance spectroscopy in a medical research application? You like it simple, precise and fast and you don't want to worry about patient safety? Then check out the Medical Research ISX-3 impedance analyzer.

It bases on our ISX-3 impedance analyzer. It is equipped with Sciospec’s IF frontend with 4-port BNC interface supporting simple 2 point measurements, as well as 3 and 4 electrode configurations. Within the measurement range from DC to 10MHz it covers a dynamic range of 180dB (Ohm…GOhm) resulting in a base precision better than 0.1%.

Additionally the Medical Research ISX-3 includes measures for enhanced electrical safety including medical grade isolation enabling a safe operation of the instrument in medical research settings.

The ISX-3 impedance analyzer is not a medical product and as such its intended purpose does not include diagnosis and/or treatment of patients. But the Medical Research ISX-3 includes several added safety measures specified in accordance with DIN EN 60601-1:2013-12 "Medical electrical equipment – Part 1: General requirements for basic safety and essential performance". These measures ease the application for excemptions for experiments on patients.

Medical grade safety features

enclosure: prevention of contact between electrical circuitry and external equipment or humans, shielding of measurement frontend (noise reduction) and mechanical safety

medical grade power supply: mains power supply from external, isolation of internal circuitry in safe extra low voltage domain (SELV) from mains voltage domain

isolated Full speed USB interface: fullspeed USB port for instrument control and data readout from PC

Ethernet interface: standard RJ45 Ethernet interface for remote control of the instrument
- The interface is not internally isolated. An external medical grade network isolator (included in the offer) can be inserted in the communication path to ensure safe isolation ratings.

IsoIO module: low level communication interfaces including hardware synchronisation and flexible programmable IO standards including serial (UART, SPI, I2C) for use of the instrument with other external equipment

AC coupling frontend: External module for AC coupling of measurements ports. Blocks DC currents and adds a high pass filter characterisitic limiting low frequency currents. Isolates the instrument galvanically from the measurement object or patient interface.

Standard Interfaces

The ISX-3 is controlled via High Speed USB or Ethernet. Optionally wireless LAN is available. The ISX-3 comes with Sciospec’s PC-based software for graphical configuration and data analysis. Additionally the system can be completely controlled the Sciospec Com-Interface. Custom code in Java and C are just as possible as the integration in LabView or Matlab.

Sync Ports

synchronize with the rest of the world

For synchronization with other devices and integration into more complex laboratory setups fully isolated ultra fast and highly flexible programmable hardware synchronization through sync in/out connectors (digital) is available as hardware option.

IOport

For simple lab automation and control/read out of additional hardware or sensors the ISX-3 can optionally be equipped with the IOport. This is a D-Sub-Micro-D connector with 8 digital IOs and 2 temperature sensor connections. As with the ExtensionPort the digital IOs can also be configured as serial interfaces (I2C, UART).

ExtensionPort System

For flexible extension of its application possibilities application specific frontends and adapters can be connected through the ExtensionPort system. Interface and specifications for the ExtensionPort are fully user accessible dramatically simplifying customer`s developments for and with the ISX-3. 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).
