AWG2021 Service Manual
This section contains information needed to manually adjust the AWG2021
Arbitrary Waveform Generator.
The Adjustment Procedures section consists of two subsections:
H Before Adjustments. Provides general information about adjusting the
AWG2021 and the Performance Check/Adjustment disk files.
H Adjustments. Procedures for manually adjusting the AWG2021.
Use the Adjustments subsection to return the AWG2021 to conformance with
performance specified in section 1, Specifications. This procedure is not required
to verify AWG2021 performance; for performance verification procedures see
section 4, Performance Verification.
Use the following guidelines to determine when to do these adjustments:
H Adjustment Interval. Generally, these adjustments should be done every 12
months.
H Adjustment After Repair. After the removal and replacement of a module due
to electrical failure, do the adjustment procedures in this section.
Before doing the adjustments, note the following requirements.
H Personnel. Only trained service technicians should perform these procedures.
H Access to Adjustments. The cabinet must be removed and additional
ventilation must be provided when making the adjustments in this procedure.
See Adjustment Instructions in this subsection for detailed information.
H Warmup Period. This AWG2021 requires a 20 minute warmup period in a
20° C to 30° C environment before it is adjusted. Adjustments done before
the operating temperature has stabilized may cause errors in performance.
H Internal Calibration. Calibrate the AWG2021 using the internal calibration
routine. See the subsection, Self Tests, in section 4 for instructions.
H Performance Check/Adjustment Files. These adjustment procedures require
loading a file from the Performance Check/Adjustment disk included with
this manual. See Adjustment Instructions in this subsection for information
about this file.
H Test Equipment. Table 5–1 lists all test equipment required to adjust the
AWG2021.
