Preview Questions Field Support Engineer | Role Specific Skill

Question 1: For a multi-channel data acquisition system that loses signal synchronization at the client's environment, which on-site diagnostic step determines if cable routing near EMI sources is causing timing skew?

Which action should you take?

Choose only one option

Check software sync settings remotely

Only change DAQ hardware modules

Try different firmware versions off-site

Re-route cables away from suspected EMI sources on-site, then run synchronization tests and compare skew before and after cable relocation

Question 2: How would you handle a situation where the client is unhappy with the resolution, but the issue is out of your control?

Which action should you take?

Choose only one option

Deflect the responsibility to the manufacturer or supplier

Empathize with the client, explain the situation clearly, and offer to escalate the issue

Offer an apology and escalate the issue to a higher authority

Avoid confronting the client's dissatisfaction and conclude the call

Question 3: A high-speed data logger at the client's site intermittently fails to record data during peak operations. Which troubleshooting step ensures the issue is not due to thermal throttling or power supply instability?

Which action should you take?

Choose only one option

Ignore the issue if occasional

Use thermal sensors to monitor the logger's temperature during peak operations and check the power supply voltage stability under load with a digital oscilloscope

Replace the data logger without testing

Reduce the data logging frequency to see if it helps

Question 4: In setting up a multi-channel oscilloscopes system for PCB testing, which calibration step ensures accurate cross-channel timing alignment?

Which action should you take?

Choose only one option

Perform a simultaneous calibration using a time-correlated test signal and verify channel alignment using a time delay measurement tool

Calibrate each channel separately without synchronization

Use factory defaults and ignore discrepancies

Adjust timing based on visual inspection of waveforms

Question 5: When setting up a controlled environment chamber for PCB testing, which parameter must be meticulously documented to maintain test repeatability?

Which action should you take?

Choose only one option

Operator shift schedules

External weather conditions

Room lighting conditions

Ambient temperature and humidity settings, along with their calibration records and sensor placement diagrams

Question 6: A system with several interconnected boards has stopped functioning. What is your first diagnostic step?

Which action should you take?

Choose only one option

Inspect the interconnection wiring for damage

Perform a software reset of the system

Replace the suspected faulty board

Check the power supply levels to all boards
