This section contains information needed to manually adjust the
AWG510 and AWG520 Arbitrary Waveform Generators.
The section consists of two subsections:
 Before Adjustments. Provides general information about adjusting the
waveform generator and the Performance Check/Adjustment disk files.
 Adjustments. Procedures for manually adjusting the waveform generator.
Use the Adjustments subsection to return the waveform generator to conformance

required to verifywaveform generator performance; for performance verification
procedures refer to Section 4, Performance Verification.
Generally, these adjustments should be done every 12 months.
After the removal and replacement of a module due to electrical failure, do the
