Open Tester Architecture

The open structure of the MTS tester family gives the user a flexible integration platform. The architecture allows the user to integrate custom solutions, third-party solutions or third-party tools into the final test solutions.


Through the User Test module, the user has the capability of adding their own hardware by placing it on a carrier board and plugging it into the tester. Digitaltest provides the CAD data for the User Test module, allowing the user to add it to his own hardware design. The custom user hardware is kept separate from the Unit Under Test via the relays on the carrier board.


Along with the ability to add custom hardware, the MTS family also provides the flexibility to write test commands for the hardware contained on the carrier board. Through the Microsoft Visual Basic programming tools, the user can easily expand the CITE test language.

By offering users the ability to add both custom hardware and test commands, Digitaltest provides customers with the tools needed to optimize the testing process.


The MTS30 is Digitaltest’s 19" rack mount In-circuit test system. The system offers the ability to perform both analog and digital tests in a chassis that can be configured in a “rack and stack” mode. Additionally, the MTS30 can also include another 19" rack capable of holding up to 6 UPS power supplies.

Despite its small footprint, the MTS30 includes 4 slots that can accommodate up to 512 analog pins or 256 hybrid pins. The system can also include the MPF flash programming module which provides on-board programming for serial or parallel components.

Typical applications

• As the In-Circuit Module in a Rack and Stack system
• Analog In-Circuit test and Digital In-Circuit test
• Modular system configuration
• Multiple test head arrangement

Concurrent Testing – An Intelligent Solution

As component densities have increased, board sizes have decreased, making it more common to build multiple boards on a single panel. However, the trade-off of having many boards on a single panel is the lengthy test times and their negative impact on line speed. In many cases, the lengthy test times are a direct result of programming large amounts of data into the UUT. However, Digitaltest offers an intelligent solution that can easily be applied to increase test throughput without compromising test quality. By integrating several MTS30 test systems into a single test rack, users have the ability to test several boards on the panel simultaneously. All the MTS testers communicate together, either through serial ports or Ethernet, to exchange test results. One master (user defined) will generate the final datalog file for the whole panel.

The automotive industry is a good example of this scenario - long test procedures are used to guarantee high fault coverage at the board test level. At the same time, throughput becomes an issue and is further complicated because the cycle time is always based on the production machines rather than the time required for test. By using the concurrent test concept, the test throughput can be adapted to the cycle time of the line regardless of the intensity of the test requirements.

Besides in-circuit testing, the automotive industry also requires intensive functional testing, which is one of the strengths of the MTS tester family.

A typical automotive test application requires:

• In-line solutions
• High throughput
• Fast, stable and reliable measurements
• Communication with in-line host PC and software
• Panel and version handling
• On-Board programming with handling of internal data through database
• Bus communication such as CAN or one of the similar buses
• Boundary Scan testing
• Logging of all (or some) measurements for quality assurance purposes

The MTS tester family provides excellent performance, the highest possible fault coverage and maximum throughput for the rigorous testing requirements of automotive manufacturers and suppliers. That is why over 80% of the automotive companies in Germany and over 90% in Australia rely on MTS testers every day.

Typical Test Application

Today’s quality requirements, and the required fault coverage for a typical board (e.g. automotive industry), may consist of the following:

• Identifying the barcode or Datamatrix code of the board
• Reading the board serial no.
• Identification of board type and board version
• Prompting the user to install the right fixture
• Automatic loading of the correct test program for the UUT
• Analog and digital In-Circuit testing
• Powering up the UUT
• Measuring current consumption of the UUT
• Power up test for voltage regulator and similar components
• Measuring of voltages, frequencies and time intervals
• Micro-controller programming through serial data entry
• Programming any flash memory on the board
• Programming board-specific information (e.g. board ID) in a specific memory cell
• Communication via serial bus (CAN bus or similar)
• Checking that the communication to the board was successful by reading some data or performing measurements
• Test of stepper-motor controllers
• Send specific commands via the serial bus – check motor signals for amplitude, timing, frequencies (via FTU/MFTU)
• Calibration of basic-frequency (for the real-time clock)
• High accuracy/resolution measurement of reference frequency of PCB
• Calculate correction data
• Write/verify correction data to EEPROM
• Calibration of fuel indicator:
     ♦ High accuracy/resolution simulation of transducer via R-Decade
     ♦ Verify applied resistance with powered PCB
     ♦ Calculate correction data
     ♦ Write/verify correction data to EEPROM
• Using vision testing to check LED’s on the board to verify the correct color and the right intensity
• Saving relevant measurement data under the board ID for later verification.

However the test program migration can go beyond just the translation of the test program. An adapter can be used to use an existing test fixture on the MTS testers for example:

• Adapter to use GR227X and 228X on MTS300 Sigma
• Adapter to use Agilent 3070 on MTS300 Sigma
• Adapter to use Rohde and Schwarz fixtures on MTS300 Sigma
• Adapter to use Marconi 80R on MTS300 Sigma
• Adapter to use Schlumberger S730,S750 and S790 on MTS84X tester.
Note that there is no adapter required to use an existing Tescon fixture on MTS180.
