FFT Calculation Types

9.5 FFT Calculation Types

Calculation types and display examples

Linear spectrum

The instrument performs a calculation using strength of input signals within each frequency band to

plot it on a frequency-domain graph.

Main uses:

To analyze peaks of frequency components of a waveform

See “Calculation types and internal calculation formulas” (p. 254).

Description

Horizontal axis

(X-axis)

Linear

Indicates a frequency on a linear scale.

Logarithmic

Indicates a frequency on a logarithm scale.

Vertical axis

(Y-axis)

Amplitude (linear)

Indicates analyzed data on a linear scale.

Amplitude (decibel) Indicates analyzed data in decibels. (Reference of 0 dB: 1 eu)*
Real part (linear)

Indicates the real part of analyzed data.

Imaginary (linear)

Indicates the imaginary part of analyzed data.

* (Eu: engineering unit) The level is calculated using a reference value in terms with an engineering unit

presently set.

(For example, when the unit is set to volts, 0 dB is equivalent to 1 V.)
