Testing and Evaluation
Aside from specialized electronic signal analysis and signal verifications, we can provide component and product level testing and even custom test fixtures. We commonly make detailed reports on our findings and make recommendations for improvements.
TIMING AND SIGNAL ANALYSIS
Here we a testing and reporting on the skew variance in a mechanical quadrature encoder.
Sometimes a high degree of precision is expected.
Whether audio performance, power supply noise, or filter characteristics, we can measure up!
Informative reports can include captures of dramatic measurements!
QUARTZ THERMOMETER ACCURACY
An oldie but a goodie that simply has not been out done in decades! That's 0.0001 degrees resolution! We use it for accurate thermal characterizations.
Here we are determining the thermal resistance of an enclosure to calculate worst case internal temperatures. A simple but important determination.
We prefer to verify the "actual" performance of our TVS protection devices, zener diodes, and FET/MOSFET devices!
Good signal acquisition is key to finding those fleeting or transient conditions that can cause problems. We're prepared!
Of what use is the MKS system if you don't have the K under control?
LOGIC AND TIMING
Logic analyzers, we have a collection of specialized analyzers: pattern generating, deep memory, high channel count, high state capture rates.....
Some instruments have performance that is truly stunning! We like to design and test with confidence!
Being able to communicate information at the fringes of our core services has been very useful!
GET THE BALANCE RIGHT!
Yes, that's milligrams! Who knows what technical problems we might be up against?
CIRCUIT AND TRANSDUCER STIMULUS
Sometimes simulating a signal condition can test for unusual case conditions. Arbitrary signal generators can help!
RF signal generators, spectrum analyzers, and sniffer probes help with RF situations!
Problems with a design? Maybe it's a component level problem; we'll check!
TIME CRITICAL MEASUREMENTS
Understanding the variance of time critical operations, is worth the time.
VECTOR SIGNAL ANALYSIS
Did you know that these signal analyzers also do sweeping characterizations of device frequency response? Great for filter and RF tunings!
FFT SIGNAL ANALYSIS
Our signal analyzers have been used for precise audio analysis and signal quality, power supply switching noise reduction, vibration analysis, and filter and device characterizations.
CUSTOM PROGRAMMING AND TEST FIXTURES
We also design and fabricate programming and test fixtures for production line environments.
CUSTOM TESTER ASSEMBLY IN PROGRESS
Here we are working on the final assembly of the internals of a relatively simple bed of nails programmer and tester we designed.
CUSTOM TESTER INTERNALS
Here we are working on the internals of a high current, high voltage, test fixture.
ANOTHER CUSTOM TESTER
The internals of a fully custom tester. We designed the test requirements, the hardware, the PCB's, and the test firmware!
SIMPLE TEST FIXTURE
Sometimes the test fixture requirements are very basic. We can accommodate small to medium test fixture designs.
MICROSCOPES FOR PRECISION MEASUREMENTS
Microscopic measurements and analysis are no longer an option for an electronics lab.
Here we have constructed an acoustically sensitive device tester.
MULTISTAGE GO-NO-GO TESTER
Completely integrated device test fixtures.
SPECIAL ENVIRONMENT TESTING
Gas sensors, PIR sensors, Acoustic Sensors, we can do specialized testing.
OPEN FRAME BON TESTERS
We have done many low cost open frame BON fixtures.
Here we are evaluating the IR reflectance characteristics of trackballs.
Specialized IR specular reflectance investigation
