Advanced
measurement
Advanced measurement (page40) mainly refers to the
operation using the result obtained from one or more of
the basic measurement.
Common attribute: refresh rate
Background
Refresh rate defines how frequently GDM-8200 series
captures and updates the measurement data. Faster
refresh rate yields better accuracy but lower resolution.
Slower refresh rate yields lower accuracy but higher
resolution. Consider these trade-offs when selecting the
refresh rate.
