parameters are used by the multimeter to calculate time-out values and
sampling parameters. When using level triggering (default mode), if the input
signal is removed during a reading and does not return within the time limits,
the measurement method changes to random so that the reading can be
completed. (After the reading, the measurement method returns to SYNC.) For
synchronous ACV or ACDCV, it is very important that the specified bandwidth
corresponds to the frequency content of the signal being measured.
bandwidth parameters are used to determine the amount of time needed for
autoranging. For these measurements, it is very important that the specified
bandwidth (especially low_frequency) corresponds to the frequency content of
the signal being measured.
