Introduction: Why Oscilloscope Calibration Is a Must for Precision Electronics and RF Work

Whether you’re debugging a high-speed serial bus, analyzing an RF waveform, or validating timing in mission-critical embedded systems, oscilloscopes are one of the most important tools in any electronics lab. However, an oscilloscope that isn’t properly calibrated can misrepresent voltage levels, distort timing measurements, and lead to flawed product designs or failed regulatory audits.

At Aumictech, we specialize in the repair and calibration of oscilloscopes used in industries ranging from aerospace and defense to telecom, automotive, semiconductor testing, and academic research. Our services are fully NIST-traceable, and we support oscilloscopes from all major manufacturers — including Tektronix, Keysight (Agilent/HP), LeCroy, RIGOL, GW Instek, Siglent, and Rohde & Schwarz.

Types of Oscilloscopes We Calibrate

Aumictech is equipped to calibrate a wide range of oscilloscope types, including:

Digital Phosphor Oscilloscopes (DPO)

• High refresh rate and visual persistence
• Used in signal integrity and eye diagram analysis

RF Oscilloscopes

• 2 GHz to 33 GHz bandwidth
• Real-time spectrum analysis and transient capture
• Used in telecom, radar, and advanced R&D

USB and Modular Scopes

We also support older and legacy models no longer serviced by OEMs.

Why Oscilloscope Calibration Is Critical

Oscilloscopes age. Internal components such as ADCs, reference voltages, time base crystals, and attenuators drift over time due to temperature cycles, power-on hours, mechanical stress, and aging.

Without calibration, you may experience:

• Voltage offset errors
• Incorrect time base scaling
• Jitter in trigger timing
• Poor rise/fall time measurements
• Amplitude linearity errors
• Inaccurate frequency display
• Inconsistencies between channels

This not only affects product quality and troubleshooting accuracy but can invalidate compliance test results (e.g., FCC, CE, ISO/IEC, automotive EMI/EMC, MIL-STD testing).

Aumictech’s Oscilloscope Calibration Process

We follow a thorough, 6-step calibration workflow, combining industry best practices and NIST-traceable standards to ensure your scope is compliant and performing to spec.

Step 1: Visual and Functional Inspection

• Front-panel control check
• Display and touchscreen functionality
• Probe connector integrity
• Fan and PSU check
• I/O port diagnostics (USB, GPIB, LAN)

Step 2: Pre-Calibration Test

• Capture waveform from known source
• Measure vertical and horizontal deviation from standard
• Save user configurations and backup firmware (if needed)
• Review of internal self-test logs (many scopes log internal errors)

Step 3: Vertical Calibration (Amplitude)

• Apply calibrated voltage steps (e.g., 10 mV to 10 V)
• Validate across all ranges and channels
• Calibrate DC gain, offset, and vertical linearity
• High-frequency amplitude flatness validation (for >500 MHz scopes)

Step 4: Horizontal Calibration (Time Base)

• Inject precision clock and frequency references
• Validate time/div accuracy from ns to s range
• Calibrate jitter margin, sweep timing, and skew across channels
• Use rubidium-standard or GPS-disciplined 10 MHz source (optional)

Step 5: Trigger System and FFT Functionality

• Validate trigger sensitivity, edge detection, pulse width thresholds
• Test advanced trigger types (e.g., runt, glitch, rise/fall time)
• Validate FFT bandwidth accuracy and spectrum baseline (for RF scopes)

Step 6: Post Calibration & Documentation

• Compare results to OEM specifications
• Create and issue a NIST-traceable calibration certificate
• Include test points, deviation, technician initials, and due date
• Optional: Before/After comparison report
• 90-day service warranty

Optional Services We Offer

• Full oscilloscope repair and restoration
• Replacement of damaged BNC/SMA connectors
• Re-capping of internal power supplies (common in aging Tek/HP models)
• Firmware updates or restoration for legacy models
• Touchscreen panel replacement
• Calibration of oscilloscope probes (passive, active, differential)

Calibration Interval Recommendations

• General lab use: every 12 months
• Mission-critical or QA testing: every 6 months
• Post-repair or reconfiguration: immediate calibration required
• Pre-audit: ensure calibration within audit window

We offer automatic annual reminders and multi-instrument bundle plans for labs and businesses.

Final Thoughts

Oscilloscopes are the eyes of your electronics lab. But even the best scope is only as reliable as its last calibration. Don’t trust your designs, tests, or compliance audits to a misaligned instrument. Let Aumictech ensure accuracy, compliance, and confidence — one waveform at a time.
