4.9. Scale/Div
Only in Log scale mode, set the logarithmic units and scale value per vertical grid division on the
display.
Key points:
 Trough changing the scale, the displayed amplitude range is adjusted.
 Amplitude range can be displayed:
Min：Reference level – 10 × scale ；
Max：Reference level
 You can modify this parameter by numeric keys, knob and arrow keys. For more details, please
refer to “Parameter Input”.

4.10. Scale Type
Set the scale type of Y-axis to Lin or Log, the default is Log.
Key points:
 In Log scale type, Y-axis denotes the logarithmic coordinate, top grid shows reference level, and
the grid size is equal to the scale value. The unit of Y-axis will be switched to be dBm as default
when the scale type is changed from Lin to Log.
 In Lin scale type, Y-axis denotes linear coordinate, top grid shows reference level and bottom
grid is 0V, the grid size is10% of the reference level and scale setting is invalid. The unit of Y-
axis will be switched to be Volts as default when the scale type is changed from Log to Lin.
 Scale type will not affect the unit of Y-axis.
