[Auto Scale]
● Menu description: the instrument automatically sets parameters like reference level and scale/division
based on input signal sizes. When this soft menu key is pressed, the instrument performs one auto scaling.
Setting rule for auto scaling: firstly obtain the maximum value and the minimum value based on current
measurement trace data. Based on the maximum value, place on the 80% graticule of the screen trace Y
axis for auto setting of reference level and scale/division.

[Y Axis Unit]
●
More description: to select the Y Axis unit from [dBm], [dBmV], [dBmA], [W], [V], [A], [dBμV] and
[dBμA]. The instrument will automatically calculate the trace data and marker readout based on the Y
axis unit.

[Ref Level Offset ]
● Menu description: to introduce offset for all amplitude readout (e.g, reference level and marker
amplitude). It will not change the trace position on the screen. This offset unit is dB and is not affected by
the scale and unit. Use number keys, stepping keys or knob to input the offset value.
