Key Points:
 By changing the scale, the amplitude range available is adjusted.
 The range of the amplitude that can be displayed:
Minimum: reference level – 10 × the current scale value
Maximum: the reference level.
 You can modify this parameter using the numeric keys, knob or direction keys.
For more details, please refer to “Parameter Setting”.
Table 2-9 Scale
Parameter
Explanation
Default
10 dB
Range 0.1 dB to 20 dB
Unit dB
Knob Step Scale ≥ 1, step = 1 dB
Scale < 1, step = 0.1 dB
Direction Key Step in 1, 2, 5 sequence
Scale Type
Set the scale type of Y-axis to Lin or Log. The default is Log.
Key Points:
 In Log scale type, the Y-axis denotes the logarithmic coordinate; the value
shown at the top of the grid is the reference level and each grid represents the
scale value. The unit of Y-axis will automatically switch to the default unit
(dBm) in Log scale type when the scale type is changed from Lin to Log.
 In Lin scale type, the Y-axis denotes the linear coordinate; the values shown
at the top of the grid and the bottom of the grid are the reference level and 0
V respectively. Each grid represents 10% of the reference level and the scale
setting function is invalid. The unit of Y-axis will automatically switch to the
default unit (Volts) in Lin scale type when the scale type is changed from Log
to Lin.
 The scale type does not affect the unit of Y-axis.
