5. Performance Verification
5.1 Introduction
This chapter contains procedures suitable for determining if the WaveSurfer 400
Series of Digital Storage Oscilloscope performs correctly and as warranted. They
check all the characteristics listed in subsection 5.1.1.
In the absence of the computer automated calibration system based on LeCroy
Calibration Software (Calsoft), this manual performance verification procedure can
be followed to establish a traceable calibration. It is the calibrating entities’
responsibility to ensure that all laboratory standards used to perform this procedure
are operating within their specifications and traceable to required standards if a
traceable calibration certificate is to be issued for the WaveSurfer 400 series Digital
Storage Oscilloscope.
5.1.1 List of Tested Characteristics
This subsection lists the characteristics that are tested in terms of quantifiable
performance limits.
• Input Impedance
• Leakage Current
• Peak to Peak noise level
• Positive and Negative DC accuracy
• Positive and Negative Offset
• Bandwidth
• Trigger Accuracy
• Time Base Accuracy
5.1.2 Calibration Cycle
The WaveSurfer 400 series Digital Storage Oscilloscope requires periodic
verification of performance. Under normal use (2,000 hours of use per year) and
environmental conditions, this instruments calibration cycle is 12 months.
