3.3.11 LEVEL Key (Frequency Level)
This section describes the menu (1/2) displayed when the LEVEL key is pressed.
Ref Level
Allows you to set the reference level.
ATT AUTO/MNL
Toggles the input attenuator between AUTO and MNL.
AUTO:
Automatically sets an optimum input attenuator in ac-
cordance with the reference level setting.
MNL:
Allows you to set an input attenuator within a range of
0 to 50 dB (in 5 dB step) for the R3132/N; within a
range of 0 to 75 dB (in 5 dB step) for the R3162.
Setting the attenuation to 0 dB is possible only by using
the numeric keys.
NOTE:
When Hi Sens ON/OFF is turned on, the input
signal range is between 0 and 30 dB.
dB/div
Displays the dB/div menu, which includes amplitude scales (for
the vertical axis) and is used to display data in logarithmic scale.
10dB/div
Sets the amplitude scale (vertical axis) to 10 dB/div.
5dB/div
Sets the amplitude scale (vertical axis) to 5 dB/div.
2dB/div
Sets the amplitude scale (vertical axis) to 2 dB/div.
1dB/div
Sets the amplitude scale (vertical axis) to 1 dB/div.
Linear
Displays the reference level data between 0 V and the REF level
on a linear scale (in volts).
Units
Displays the Units menu which sets the units used for the refer-
ence level, the display line and the marker level.
