Spectrum window
Below the spectrum field (A) are functions (B) which are reached using the instrument function keys
in combination with the SHIFT key.
The spectrum diagram is marked with the (displayed) range (1) in Hz, CPM or Orders, depending on
the default setting made under ‘General settings’. The unit may be changed by pressing F4, ‘Hz/CPM/
Orders’ (2). All spectrum lines below the lower frequency will be shown in grey.
The Y axis (3) is marked with the measuring unit for spectrum line amplitude and with the range. For
default measuring assignments (which are not part of a measuring round downloaded from Cond-
master), the spectrum type unit can be changed by pressing the MENU key while
in the measurement
window
and selecting ‘Measuring point data’.
If there are known disturbances, e.g. from surrounding equipment, the ‘Spectrum enhancement’ func-
tion can be activated in Condmaster in order to obtain a clearer view of the relevant signals in the spec-
trum. Using this function, spectrum lines related to a certain source of disturbance can be excluded, or
interesting spectrum areas highlighted. When ‘Spectrum enhancement’ is activated in Condmaster, it
can be turned on or off in the Leonova spectrum window under MENU > ‘Spectrum enhancement’ (4).
Zoom options become available by pressing F1, ‘Zoom’. While in zoom mode, use MENU or SHIFT to select
a suitable zoom option. The spectrum can be zoomed along its X axis with the LEFT/RIGHT arrow keys.
Pressing F2 (‘Cursor’, (5)) displays options for cursors, harmonics and stroboscope. Holding down the
SHIFT key while in the cursor menu displays sideband options.
To display symptoms, press SHIFT + F4 in the spectrum window.
