General Signal Viewing > DPX Spectrum Scale Tab
Scale Tab
The Scale tab allows you to change the vertical scale settings and set the color scheme used for the Bitmap
trace. Changing the scale settings changes how the trace appears on the display but does not change
control settings such as Measurement Frequency.
Setting Description
Vertical Controls the vertical position and scale of the trace display.
Scale Changes the vertical scale.
Offset Adjusts the Reference Level away from the top of the trace display.
Reset Scale Sets Scale to its default value and Offset to zero. Disabled when Units (Setup > Analysis
> Units) is set to Watts or Volts.
Autoscale Resets the scale of the vertical axis to contain the complete trace. Disabled when Units
(Setup > Analysis > Units) is set to Watts or Volts.
Horizontal Controls the horizontal position and scale of the trace display.
Scale Changes the horizontal scale.
Position Adjusts the horizontal position of the signal. This does not change the center frequency.
Autoscale Resets the scale of the horizontal axis to contain the complete trace.
DPX Bitmap Controls the appearance and scale of the Digital Phosphor Bitmap trace.
Color Allows you to select the color palette used for the Bitmap trace.
Max Sets the hit density represented by the top of the color scale. "Clipping" occurs for
densities greater than this value.
Range: 1p% - 100%; Default: 100%.
Min
Sets the hit density represented by the bottom of the color range. Range: 0 - 80%;
Default: 0.
Curve Adjusts how colors are mapped to the signal density. The mapping can be linear (Curve
= 1), or it can be set to concentrate the resolution on the lower level of the range (Curve >
1) or the mapping can be set to show the best resolution on the upper range of density
or hit count (Curve < 1).
Auto Color Adjusts the Max and Min settings to display the broadest range of colors.
