Function Description / Comments

12 Transfer Function Activates additional buttons for the Transfer Type options. The 6

buttons appear in the toolbar area between buttons #15 and #21

when the Transfer Function button is clicked on [they are not

shown in the above figure]. The Transfer Function buttons are:

Inertance, which is: Acceleration divided by Force.

Mobility, which is: Velocity dived by Force.

Compliance, also known as Receptance, which is:

Displacement divided by Force.

Apparent Mass, which is: Force divided by Acceleration.

Impedance, which is: Force divided by Velocity.

Dynamic Stiffness, which is: Force divided by

Displacement.

Transfer function displays assume the reference channel is a

force channel. You MUST define the response channels to be

the correct type of data (acceleration, velocity, or displace-

ment) that you are acquiring. Define these in the data type

column of the Calibration window. This allows the data to be

integrated or differentiated correctly to derive the desired

transfer function.

13 Averaged Time A single-channel display function. Displays a time domain

waveform of filtered, averaged, sampled data scaled in either Volts

or EUs.

14 Negative Spectrum Reference Spectrum minus Current Spectrum displays the

difference between the Reference Spectrum and the Current

Spectrum when the following is specified: Linear (-),

Negative Averaging

15 Windowed Time Applies to the FFT Response window specified in the Miscellaneous

Tab of the Configuration window to time data.

16 Full Octave Extends from a lower frequency, f

2 to twice the lower frequency

(2f

). The <Full Octave> button is only actie when the <Octave>

button (#11) is selected.
