corrected.
Ref level
Key access:
[AMPTD] > {Ref level}
Activates the reference level function.
The reference level is the amplitude power or
voltage represented by the top graticule on the
display. Changing the value of the reference level
changes the absolute amplitude level (in the
selected amplitude units) of the top graticule line.
To change the reference level, use the arrow keys,
the knob, or the numeric keypad. Pressing any
digit (0 through 9) on the numeric keypad brings
up the terminator menu.
Attenuation
Key access:
[AMPTD] > {Attenuation}
Toggles the input attenuation between
Auto
or
Man
.
The input attenuation ranges from 0 dB to 50 dB
and allows you to set the attenuation level in 1 dB
increments when attenuation is set to
Man
.
The input attenuator, normally coupled to the
reference level control, reduces the power level of
the analyzer input signal at the input mixer. The
attenuator is recoupled when attenuation is set to
Auto
.
CAU-
CAUTION
To prevent damage to the input mixer, do not exceed a
power level of +30 dBm at the input. A granted power
level for stable sensitive measurement is less than
20 dBm.
