Pop up menus related to parameter setting of Amplitude, including [Reference Level], [Attenuator

], [Preamplifier ON OFF],
[Scale Type Logarithm Linear], [Scale/Division], [Ref Unit], [Ref Offset]. Please refer to following diagram for the menu structure.

Ref Level
Menu description: The reference level can be adjusted with the number keys, step keys or knob. The reference level
corresponds to the top of the coordinate top. Measure signal at reference level position to get highest accuracy. The input
attenuator of the signal/spectrum analyzer is coupled to the reference level, which can be automatically changed to avoid
compression of input signal.

[Attenuator Auto Man ]
Menu description: In the manual mode, set attenuator to lower the distortion of large signal. Maximum can be set to 39dB

[Preamplifier ON OFF]
Menu description: to control the ON OFF status of the preamplifier. Preamplifier is provided as a standard component.

[Scale/Div]
Menu description: to select the scale/division 1, 2, 4, 10dB/division. This menu is only valid when the scale type is logarithm.

[Scale type Log Lin]
Menu description: to select the Y Axis Scale Type as Logarithm or Linear. In general, the logarithm scale unit is dBm and the
linear scale unit is mV. Other unit types will be manually selected through the [Ref Unit].

[Ref Unit]
Menu description: to select the Ref unit from [dBm], [dBuW], [dBpW], [dBmV], [dBuB], [W], [V]. The instrument will automatically
calculate the trace data and marker readout based on the Y axis scale unit.

[Ref 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.
