Description
<n> = 0.01s to 1.0s
DEFault 1.0s
MINimum 0.01s
MAXimum 1.0s
:APERture? Query programmed APERture value
The integration period (measurement speed) for Frequency and Period is set
using the APERture command (to set other basic measurement functions, see
:NPLCycle). The unit of measurement for the APERture command is
seconds.

This command is used to manually select the measurement range for the
specified measurement function. The range is selected by specifying the
expected reading as an absolute value. The Model 2016 will then go to the
most sensitive range that will accommodate that expected reading. For exam-
ple, if you expect a reading of approximately 50mV, simply let the parameter
(<n>) = 0.05 (or 50e-3) in order to select the 100mV range.
