The following settings are available in Spectrum mode only:
Unit of Magnitude........................................................................................................ 125
Reference Level.......................................................................................................... 125
Source.........................................................................................................................125
Vertical Scale.............................................................................................................. 125
Unit of Magnitude
Defines the unit in which the power values are displayed.
Remote command:
SPECtrum:FREQuency:MAGNitude:SCALe on page 357
Reference Level
Defines the expected maximum input signal level.
Remote command:
SPECtrum:FREQuency:MAGNitude:REFerence[:VALue] on page 361
Source
Selects the channel for which the captured data is analyzed. Spectrum analysis can
only be performed on one channel at a time.
The source can also be selected using the [CH1]/[CH2] keys.
Remote command:
SPECtrum:SOURce on page 356
Vertical Scale
Defines the scaling of the input signal in Volt per division.
Vertical scale and vertical position affect the resolution of the waveform amplitude
directly. To get the full resolution, make sure that the waveforms cover most of the
screen's height.
Note: This value configures the input signal. The vertical scale of the y-axis of the
spectrum, which is indicated in the channel settings beneath the spectrum diagram,
must be configured using the [RANGE] and [POS] keys.
