Advanced Measurement Overview
Background
Advanced measurement mainly refers to the type of
measurement which uses the result obtained by one of
the basic measurements: ACV, DCV, ACI, DCI, 2/4W,
Diode/Continuity, Frequency/Period, and Temperature.

Refresh Rate
Background
Refresh rate defines how frequently the GDM-8261A
captures and updates measurement data. A faster refresh
rate yields a lower accuracy and resolution. A slower
refresh rate yields a higher accuracy and resolution.
Consider these tradeoffs when selecting the refresh rate.
For DC measurements, the frequency of the refresh rate
depends on the rate settings (S, M, F) and the ADC speed
settings (Accurate, Quick) (page 92 ).
For AC measurements, the refresh rate (S, M, F) is
directly tied to the AC bandwidth settings (page 86).
For further details, please see the specifications.
