The following program configures the multimeter for period measurements on the
10 mA range from a current source. The input signal is DC-coupled.
10 OUTPUT 722;"PER 10E-3"

Specifying bandwidth
The ACBAND command specifies the frequency content of the input signal for all
AC and AC+DC measurements. Specifying the frequency content allows the
multimeter to make accurate measurements and to configure itself for the fastest
possible measurements. The ACBAND command's first parameter specifies the
lowest expected frequency component (the power-on/PRESET NORM value is
20 Hz). The second parameter specifies the highest expected frequency
