The Keysight/Agilent/HP 5508A Measurement Display is the core processing and visualization unit of the 5528A Laser Measurement System. It integrates a microcomputer to acquire, calculate, display, and output single-axis measurement data with high precision. The instrument automatically computes velocity, angular rotation, and straightness displacement when paired with compatible optics and measurement modes, making it essential for machine tool calibration, metrology research, and quality control environments.
## Technical Specifications
• **Measurement Functions:** Distance, velocity, angle, and straightness displacement
• **Display:** High-resolution graphical display with no data loss during measurement
• **Data Smoothing:** Automatic averaging to attenuate vibration and noise; user-selectable via keyboard
• **Unit Selection:** Metric (millimeters, degrees C) or English (inches, degrees F) via rear panel switch
• **Update Rates (Nominal):**
– Distance: 40/s (Auto Record), 20/s (GPIB Triggered)
– Velocity: 30/s (Auto Record), 15/s (GPIB Triggered)
