Our Sigma MTS 300 has been designed for high throughput capability and with up to 1000 measurements per second it is one of the fastest in-circuit testers on the market. The test system can check your circuit boards with up to 3456 analog, 1664 hybrid or a combination of both test points. The Sigma puts flexibility, high fault coverage and simple programming at the fore.
You can use the modular test system for analog and digital in-circuit testing, vectorless testing, functional test, boundary scan and memory programming. Thanks to the non-multiplexed pin architecture it is also possible to use fixtures and test programs from other test systems.
Fixture alignment aid
With the optional fixture alignment aid, the fixture can be easily positioned at the interface and placed using a life mechanism. The fixture runs on two rails – like a drawer – and is correctly positioned using positive stops as well as standard jaws.
The fixture alignment aid can be retrofitted on existing systems and has a load capacity of up to 400 N. The standard version is designed for a fixture size of up to 600 x 600 mm – but of course we also offer custom solutions on request.
Analog Measurement Unit – heart of the system
The AMU05 (Analog Measurement Unit 05) is the core of all our test systems. It ensures that all the measurements are performed faster, more accurately and with even greater stability.
Improves the quality of your test programs
When it comes to the test coverage of a program in the analog ICT, the question is not only whether there is a test for every component and if it was performed, but also whether the test would in fact recognize a fault.
The Analog Signal Switch Unit serves as a 6-bus interconnect for 128 pins each to the Analog Measurement Unit (AMU05) for the In-Circuit test.
128-Pin hybrid driver/sensor module
The HYB04 enables comprehensive analog as well as digital driver- and sensor-functions. It has 128 non-multiplexed hybrid pins per module.
64-pin hybrid driver/sensor module
Our HYB03 enables comprehensive analog as well as digital driver- and sensor-functions. It has 64 non-multiplexed hybrid pins per module.
Our universal carrier for function modules
All function modules are plugged into our Universal Carrier Board (UCB) – with four slots available per carrier.
Universal control outputs
The MOC is our universal control module for a wide variety of tasks, such as controlling relays in the fixture.
MRM16 / MRM04
Relays for free circuits
Our MRM is a relay card for universal connection of many kinds of signals. It serves as a basic module and is available as a variant with 16 NO relays or as a variant with 4 x (7:1) multiplex structure.
The MRD permits connection of a programmable resistor to the test object.
Stimulate and measure voltages and currents
The MSM measures and stimulates precise voltages and currents through the six bus lines or interface pins.
Potential-free voltage source
The Universal Power Controller (UPC02) provides an independent potential-free voltage source for powering the test object, whereby the output voltage and current limiting are freely programmable.
Lambda edition: real parallel testing as the solution
Would you like to test multiple boards in parallel and save time? We have the solution: real parallel testing with the Lambda edition. With this technology you can test two or more assemblies at the same time, thereby optimizing the cycle times and shortening the test time or performing the tests using the shortest path. An ICT or functional test is performed by two or more independent test heads, reducing the test time by the corresponding factor. This applies to multi-panels as well as for multiple independent single test objects.
The Lambda edition thus reduces the test time for two objects for example by 50 percent, or 75 percent for four, and so on.
Advantages of parallel testing
- Optimizes cycle times
- Small, economical test heads
- Powerful, flexible software environment
- Assemblies can be tested without additional effort
- Low hardware costs
- Takes up less space
Boundary Scan ICT
With our boundary scan upgrade for In-Circuit Tests (ICT) you can get the best of both testing methods worlds and achieve an optimal test strategy with maximum test coverage and reduced overall costs.
The CAN-/LIN modules are standard interfaces for communication with the test object.
With the Programmer Modules you can make specific selections for onboard flash programming. Here we integrate for example programmers from Ertec, SMH, ProMik or Algocraft.
IEEE-, RS232-, USB-Modules
These functional modules have standardized PC interfaces for communicating with additional function test modules.
- Standard interface uses vacuum
- Cable interface is also possible
- Basically any interface is possible using a fixture converter (e.g. Pylon or Virginia Panel)
In order to avoid long waiting times for the construction of the fixtures, Digitaltest offers an in-house fixture service.
