Switch
3-61.
The RESOLUTION, N switch determinestheamount of time that thecounter's main gate
is
open for a particular measurement when the Main Gate
FF
(see Figure 3-1) determines the gate
time. Depending on the measurement, this time results in a certain measurement resolution
(e.g., frequency measurements),
a
number of intervals averaged (e.g., T.I. AVG measurements),
a scaling factor by which the time base
is
divided (e.g., period measurements), or an integration
time (e.g., DVM measurements). Table 3-2 shows thesetting of the RESOLUTION switch and the
corresponding time the main gate is open.
