FFT Conditions (FFT Setup)
Configure the time window and how to display FFT waveforms (normal, peak hold, or average).
On models with user-defined computation (option), you can also select the spectrum to analyze.
Spectrum Type (Type/Sub Type)
On models with user-defined computation (option), you can also select the spectrum to analyze from the
following:
Spectrum Description Unit (Default value)
LS-MAG Amplitude of the linear spectrum of the specified waveform Source unit
LS-LOGMAG Logarithmic amplitude of the linear spectrum of the specified
waveform
dB and source unit
LS-PHASE Phase of the linear spectrum of the specified waveform deg
LS-REAL Real part of the linear spectrum of the specified waveform Source unit
LS-IMAG Imaginary part of the linear spectrum of the specified waveform Source unit
RS-MAG Rms power spectrum magnitude Source unit
RS-LOGMAG Rms power spectrum logarithmic magnitude dB and source unit
PS-MAG Amplitude of the power spectrum of the specified waveform Enumeration of source units
PS-LOGMAG Logarithmic amplitude of the power spectrum of the specified
waveform
dB and source unit
PSD-MAG Amplitude of the power spectrum density of the specified
waveform
Enumeration of source units
PSD-LOGMAG Logarithmic amplitude of the power spectrum density of the
specified waveform
dB and source unit
CS-MAG Magnitude of the cross spectrum of the specified two waveforms Enumeration of source units
CS-LOGMAG Logarithmic amplitude of the cross spectrum of the two specified
waveforms
• If the source units are the
same: dB and source unit
• If the source units are
different: dB
CS-PHASE Phase of the cross spectrum of the two specified waveforms deg
CS-REAL Real part of the cross spectrum of the two specified waveforms Enumeration of source units
CS-IMAG Imaginary part of the cross spectrum of the two specified
waveforms
Enumeration of source units
TF-MAG Amplitude of the transfer function of the two specified waveforms None
TF-LOGMAG Logarithmic amplitude of the transfer function of the two specified
waveforms
dB
TF-PHASE Phase of the transfer function of the two specified waveforms deg
TF-REAL Real part of the transfer function of the two specified waveforms None
TF-IMAG Imaginary part of the transfer function of the two specified
waveforms
None
CH-MAG Amplitude of the coherence function of the two specified
waveforms
None
Source unit: There is no source unit when the LinearScale unit or Math unit is not set.
When the source unit is up to two characters in length, the source unit is used.
When the source unit is more than two characters in length, "EU" is used.
