3-2 Automating Measurements
Operator Interaction
Many tests are performed by technicians, operators, or testers who
interact with the measurement system. When designing the automation
system, it is important that the system allow operators to perform the
measurement tasks quickly and consistently. The system must also be
easy to learn and easy to use, providing the user with instructions and
feedback.
The analyzer provides many features to satisfy these requirements. The
features include
• user-defined pop-up messages to prompt the operator
• on-screen graphics to create custom diagrams
• user-defined measurement channel and frequency annotation
• ability to define the key menu with frequently-used custom
softkeys
• IBASIC display window; configurable as full or split
• IBASIC DISP line and INPUT line
• data entry using a barcode reader
• data entry using an external keyboard
• hot keys on external keyboard for common functions
• operator control of measurements using a foot or hand switch
• beeper with adjustable volume and pitch
• limit test pass/fail TTL output
• user-defined TTL input/output
• output for external VGA-compatible color monitor
The following sections explain how to use these features, and show
several examples.
