4.8.2 Linear Spectrum [LIN]

Function

Horizontal

cursor

Vertical

cursor

Displays the frequency domain waveform of the input signal, including
magnitude and phase information.
Major applications include:

Determining the peaks of waveform frequency components
Determining the levels of high and low harmonics

Fa =

(fa)

= |Fa|exp(j

= |Fa|(cos

a + jsin

LIN-Hz Frequency spectrum display as linear units.

The range is from DC to the maximum frequency range value.

LOG Hz Frequency spectrum display as logarithmic units.

The range is from between 1/400 and 1/4000 of value to the
frequency range value.

Real Linear display of real-number part of the data as voltage

(Nyquist mode)

LIN-REAL Linear display of real-number part of the data as voltage
LIN-IMAG Linear display of imaginary-number part of the data as voltage
LIN-MAG Linear display of analysis data as voltage
LOG-MAG Logarithmic display of analysis data as dB

(0dB reference value: 1 V peak=2V p-p)

PHASE Degrees (deg) display of phase component of data
Imag Linear display of imaginary-number part of the data as voltage

(Nyquist mode)
