SPECTR_ENH_GENERAL_SETTINGS structure |
|
The SPECTR_ENH_GENERAL_SETTINGS structure (defined as SPECTR_ENH_GENERAL_SETTINGS_DLL when used for COM interoperability) describes the general graphical settings applied to a specific enhanced spectrum analyzer. The current settings can be obtained through the SpectrumEnh.SettingsGeneralGet method and modified through the SpectrumEnh.SettingsGeneralSet method.
For further details about using the embedded Enhanced Spectrum Analyzer refer to the SpectrumEnh class section.
For details about using the Enhanced Spectrum Analyzer refer to the How to use the Enhanced Spectrum Analyzer tutorial.
