Fiber optic transceiver

Microbox

FlexRay, CAN-FD, High Speed CAN,

Low Speed CAN, LIN, K-Line,

Low Speed Single Wire CAN,

J1850, J1708, SENT, RS232

Introduction and use

Functional tests e.g. in test-labs often require insulated FlexRay, CAN- (Controller Area Network) and LIN-busses (Local 

Interconnect Network) to control the device under test. For this purpose special transceivers are available. They allow 

bidirectional data transmission of signals via fiber optic cables and can be used during susceptibility tests at high field 

strength. Quite often these transceivers use enhanced filtering at the electrical bus connectors. This filtering affects signals 

and may have major effect on emission tests. 

Our EMCtools Microbox was designed for emission and susceptibility tests. Using multilayer technology and sophisticated 

circuit design full CAN/LIN compliance and the ability to perform tests at electromagnetic fields of 270V/m and above could 

be achieved. The handy plastic housing allows tests with limited test space. 

The EMCtools Microbox uses standard multimode fiber optic cables and allows direct connection to the electric bus (e.g. 

CAN-/LIN-Cab) via SUB-D female connectors. 

In combination with a second Microbox or one channel of our EMCtools Canbox a complete optical CAN/LIN-bus connection 

can easily be arranged. 

It is possible to build mixed CAN/LIN-bus lines with other fiber optic CAN/LIN transceiver products as described in 

“compatibility” in technical data below.

ESD Protector 

for Microbox fiber optic 

FlexRay, HS/LS-CAN and LIN transceivers

Introduction and use

ESD tests in test-labs often require galvanic insulated busses like FlexRay, CAN- (Controller Area Network) 

and LIN-busses (Local Interconnect Network) to control the device under test. For this purpose the EMCtools 

ESD-Protector and our standard fiber optic bus transceivers (Microbox) are available. They allow bidirectional 

data transmission of CAN/LIN-signals via fiber optic cables and can be used during ESD tests to protect 

Computers or Notebooks from the ESD discharge. 

The combination of ESD-Protector and EMCtools Microbox were designed for ESD discharges up to 30kV 

(HBM). 

The ESD-Protector does not affect the max. bitrate of the used bus system and can be used in 

combination with: 

1. EMCtools Microbox FlexRay 

2. EMCtools Microbox High Speed CAN 

3. EMCtools Microbox Low Speed CAN

Multi Bus Tester (MBT) 

Signal generator and receiver for 

HS-CAN, LS-CAN, Single Wire LS-CAN, LIN-Bus, K-Line and J1850-Bus 

EMCtools Multi Bus Tester (MBT)

The EMCtools Multi Bus Tester simulates an automotive Device under Test (DUT) including cable harness and 

Load-Box inside and a separate stimulator outside the EMC chamber. Based on an analysis of commonly used 

bus systems in automotive tests, the EMCtools MBT provides the possibility to test six different field bus systems: 

1. High Speed CAN 

2. Low Speed CAN 

3. Low Speed Single Wire CAN 

4. LIN-bus 

5. K-Line (L-Line)

6. J1850 (class B) 

The MBT-set consists of a Master and a Slave unit, a load simulator with cable harness and includes cables for 

wiring. The Slave unit (DUT) controls 4 bulbs in a load simulator connected to the Slave unit via a cable harness 

of approx. 190cm length acc. ISO11451-2 immunity and CISPR25 emission standards. The Slave unit requires a 

supply voltage of 9 – 15 Volts from a symmetrical LISN (Line Stabilization Network or Artificial network) or 2 LISN 

(remote ground acc. ISO 11452-2). 

The Slave unit is controlled by a second device outside the EMC chamber, the Master unit. This Master unit 

sends bus messages to switch on and off the lights on Slave unit inside the EMC chamber. The Slave unit (DUT) 

loops back the received bus messages to the Master unit via fiber optic bus and the slave unit then activates 

LEDs on the Master unit rear panel to show the proper function of the Slave unit (DUT) and the fiber optic 

transmission and communication. 

The MBT Master unit provides a trigger signal for “bus fail” and “error frames”. 

The EMCtools Multi Bus Tester MBT in combination with EMCtools Microboxes has been tested for: 

BCI tests (ISO 11452-4): 

Calibration method 0.1 – 400 MHz 300mA CW/AM 1kHz 80% 

RI tests (ISO 11452-2) 

Calibration method 200 – 3300 MHz 270 V/m CW/AM 1kHz 80%/Pulse Mod.

Introduction and use:

The EMCtools Current Sensor-Set offers new possibilities in automotive EMC susceptibility tests. 

It provides a galvanic insulated DC current measurement for DUT supervision or failure detection. High rated measurement 

current and extreme low voltage drop come together with high resolution and good accuracy. The measurement head has 

been tested for field strength of >270V/m. 

The built in battery allows measurement in pos. or neg. battery line. It can be recharged by connecting it to a USB connector 

of any available PC or notebook. 

The current data is transferred to the control unit using a standard simplex fiber optic F-SMA cable. 

The control unit displays the current on a display. A trigger signal can be generated to trigger Oscilloscopes or to control the 

susceptibility test depending on various current situations. 

A CAN-bus interface provides the measured current permanently or when triggered on HS-CAN or LS-CAN. CAN-bus, CANspeed and CAN-identifier can be set individually. 

The measured current data is also available via USB. 

A built in USB to CAN interface can be used to send EMC related data like test frequency or field strength etc. to CAN bus. 

All settings and options can be made locally using a menu rotary switch or via remote commands (USB). 

Settings are stored in non volatile memory.
