AM700 Audio Measurement Set User Manual
NOTE. When running a voltage sweep, especially with Automatic Timing enabled,
the Input Range setting can be set for the highest voltage expected and Auto Range
disabled. This eliminates a possible loss of a data point due to the Auto Range
action that can occur when the sweep voltage level changes (either up or down).

Sweep Direction. Direction, Automatic Timing, and Spacing parameters are toggled
by touching the soft keys, while Count, Points per Sweep, Dwell, and Time
parameters are changed by touching the desired soft key and entering a value at the
keypad (or you can turn the large control knob). Touch the soft key to accept the
entered value (or press the Enter key). As a standard measurement practice, sweeps
are run from high to low so that data can be acquired more quickly. The default
sweep starts is set to the highest frequency in the sweep, and the sweep direction is
from Start to Stop.
