Performance Verification
This section consists of the Performance Check, used to determine compliance
with the Performance Requirements listed in the Specifications section.
Controls and connectors on the 1780R-Series front panel and rear panel are fully
capitalized (e.g., RIGHT DISPLAY-WFM). Control and connector names on test
equipment, as well as internal controls and adjustments for the instrument under
test, are initial capitalized (e.g., Time/Div).
Recommended Equipment List
The following equipment and accessory items are required to do the Performance
Check Procedure. Broad specifications are followed by an example of equipment
that meets these specifications. In most cases, the following procedure was
prepared using the recommended equipment.
