Common Issues We Repair
-
Power Issues: Unit will not power on, randomly shuts down, or shows unstable voltage rails.
-
Output Malfunctions: Incorrect signal levels, waveform distortion, or output channel failures.
-
Internal Errors: Diagnostic or self-test failures, calibration drift, or firmware lock-ups.
-
User Interface Problems: Faulty touchscreen, control knob failure, or display issues.
-
Communication Failures: Malfunctioning USB, LAN, or GPIB interfaces.
-
Noise or Ripple: Excessive output ripple often caused by aging capacitors or degraded regulation circuits.
Our Repair Process
We begin with a full diagnostic evaluation of power systems, analog output channels, and digital control logic. Issues are often traced to degraded capacitors on the power supply board or thermal damage on output modules. Our certified repair experts perform component-level troubleshooting and replace faulty op-amps, regulators, or precision resistors as needed.
After repairs, we verify the calibrator’s accuracy using NIST-traceable standards and perform final functional testing across all output ranges.
