Scaling Controls (1)


1. Reference Level Controls
The Reference level determines the bottom display boundary of a measurement. Readings below this value are considered out of scope of a view and will not be displayed.

2. Display Dynamic Controls
The Dynamic range controls the level resolution of each view, and together with the Reference level also the upper display bound (Reference level + Dynamic Range = maximum display value).

3. Cut off Level Controls
The Cut-off Level is the minimum value that should be used. Any reading below this value will be adjusted. Unlike the Reference level it affects the displayed values instead of the display area, as can be seen in the following image (Reference Level: -80 dBm, Dynamic: 10 dB, Cut off Level: -78 dBm):


4. Auto-Adjust Level Parameters
With the “Adjust-Level” button the MCS tries to adjust the above parameters to optimum values based on current readings (these may be different for each type of view). This function is also available in the context menu of each view that supports it.

5. Frequency Raster Scaling Mode
Switch between Linear and Logarithmic rasters on the frequency axis. The logarithmic raster starts at 1 Hz as the imaginary origin to compute the relative positions of raster entries, so if the current sweep settings use a high start frequency and/or a small span frequency the visual difference to the linear raster is very small. Both raster types will create entries at “logical” frequencies, e.g. the logarithmic raster might create entries at 10, 20, 50, 100, 200 and 500 MHz, while the linear raster might use 50, 100, 150, 200, 250, 300, 350, 400, 450 and 500 MHz. The frequency raster will however always include the start- and stop-frequency at the left- and right side of the raster.

6. Enable / Disable Auto-Adjust
If checked the Auto-Adjust Level Parameters will be done after each completed sweep.
