ON: Turns on the built-in pre-amplifier at the gain of 20 dB
and over. Since the gain of the pre-amplifier at each fre-
quency is corrected, no gain needs to be considered for
level measurement.
OFF: Turns the built-in pre-amplifier off.
1/2_more Displays the Level menu (2/2).
Ref Offset ON/OFF Toggles the reference level offset function on or off.
ON: Allows you to set the offset level in a range of 0 to
±100.0 dB. The relationships between the displayed
reference level, the set reference level and the offset
are shown below:
Reference level (displayed) = Reference level (set) +
Offset.
OFF: Turns off the offset.
Input 50Ω/75Ω Sets the impedance input level for the display. The 75 Ω setting is
used when a 75 Ω impedance converter (ZT-130NC) is connected
to the RF input.
The R3132 converts all levels for the 75Ω system and displays
them.
2/2_more Displays the Level menu (1/2).
