measures impedance sensing current from a dedicated QCBox ISense
output (Internal Mode is not allowed as DUT must be connected to
amplifier’s output).
Smoothing
Allows the user to select a Frequency smoothing of the active curve. The
smoothing algorithm averages all the value within the selected fraction of octave
band, surrounding each analysis Frequency. It is a non destructive post process
that can be applied or removed at any moment after the measurement has been
taken. Note: Smoothing is not active for Ohm scale and for Rub&Buzz.
11.2.3 SINUSOIDAL SETTINGS DIALOG
This is undoubtedly the most important User Interface of the entire Menu. Here the
single action of every control is considered. Theoretical and practical effects on the
subsequent measurement are considered later.
Sweep Settings
Stepped Check Box
Allows the user to choose between continuous or stepped Logarithmic Sweep.
Continuous sweep is faster; the user should have clear how this may affect the
measurements.
Speed Drop Down
Lets the user choose between Slow (max accuracy), Fast (optimized for Fast-
Track Rub&Buzz) or Normal measurement speed. The resulting sweep time
length in seconds may be read in the sinusoidal control panel status bar.
Resolution Drop Down
Lets the user choose between five different Frequency resolutions. It affects the
measurement execution time, whatever the other settings are.
Freq Max Edit Box
Lets the user define the highest Frequency of the Sweep. This is also the starting
measurement Frequency. The highest value accepted is 22388 Hz. The value
should also be one octave higher than the Minimum Frequency.
Freq Min Edit Box
Lets the user define the lowest Frequency of the Sweep. This is also the end
measurement Frequency. The lowest value accepted is 10 Hz. The value should
also be one octave lower than the Maximum Frequency.
