Techniques for Oscilloscope Calibration

Oscilloscopes are very complex instruments, mainly because of attempts to provide easy and direct access to waveforms, then to permit both qualitative and quantitative analysis.

Oscilloscope calibration verifies a number of instrument performance characteristics, including:

• Accuracy of vertical deflection
• Range of variable vertical controls
• Vertical channel switching
• Accuracy of horizontal deflection
• Accuracy of any internal calibrator
• Pulse edge response
• Vertical channels bandwidth
• Z-axis bandwidth
• X-axis bandwidth
• Horizontal timing
• Timebase delay accuracy
• Time magnification
• Delay time jitter
• Standard trigger functions
• X-Y phase relationship

This seminar examines the usual techniques and requirements for calibrating these parameters. Additionally it considers the calibration instrumentation used for doing these tests.
