You can modify this parameter using the numeric keys, knob, or
direction keys.
5.3.4 [Scale Type Lin Log]
Sets the Scale Type of Y-axis to Lin or Log, the default is Log. It
only works under internal mixer mode. In general, select mV as Lin
amplitude scale unit. Of course there would be other units for
select.
Key points:
⚫ In Log scale type: The Y-axis denotes the logarithmic
coordinates, the value shown at top of the grid is the reference
level, and the grid size is equal to the scale value. The unit of
Y-axis will be automatically switched into the default "dBm" when
the scale type is changed from Lin to Log.
⚫ In Lin scale type: The Y-axis denotes the linear coordinates, the
value shown at the top of the grid is the reference level and the
bottom of the grid shows 0 V. The grid size is 10% of the
Reference level and the Scale/Div is invalid. The unit of Y-axis
will be automatically switched into the default "mV" when the
scale type is changed from Log to Lin.
⚫
Other than as mentioned above, the unit of Y-axis is
independent of the Scale Type.
5.3.5 [Ref Offset]
Assigns an offset to the reference level to attempt to compensate
for gains or losses generated between the device under
measurement and the analyzer.
Key points:
⚫ The changing of this value changes both the readout of the
reference level and the amplitude readout of the marker, but will
not impact the position of the curve on the screen.
⚫ You can modify this parameter using the numeric keys.
⚫
This offset use dB as absolute unit, will not change with selected
scale and unit.
5.3.6 [Ref Unit>]
Sets the unit of the Y-axis to [dBm], [dBμW], [dBpW], [dBmV],
[dBμV], [W] or [V].
Key points:
1) [dBm]
