Adjustment Procedures
This section contains information needed to manually adjust the
AWG510 and AWG520 Arbitrary Waveform Generators.
The section consists of two subsections:
H Before Adjustments. Provides general information about adjusting the
waveform generator and the Performance Check/Adjustment disk files.
H Adjustments. Procedures for manually adjusting the waveform generator.
Use the Adjustments subsection to return the waveform generator to conformance
with performance specified in Section 1, Specifications. This procedure is not
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
adjustment procedures in this section.
There are six adjustment procedures, as listed in Table 5–1.
