Key Reference
Amplitude
Scale Type
Log Lin
Scales the vertical graticule divisions in logarithmic units
when
Log
is selected. The valid logarithmic units are 1, 2, 5
and 10 dB per division. When
Lin
is underlined, the vertical
divisions are linearly scaled with default amplitude units of
volts. The top of the graticule represents the reference- level
value; the bottom of the graticule represents zero volts.
(Each division is one- tenth of the reference level.)
Key access:
Ampiltude > Scale Type
Y Axis Unit
Accesses the softkeys that change the amplitude units
(logarithmic or linear). Change the amplitude units by
pressing
dBm , dBmV , dBuV , dBuA, Watts , Volts ,
and
Amps
.
Key access:
Ampiltude > Y Axis Unit
Hi-Sensitivity
Set this softkey to
On
to set 0 dB attenuation, - 50 dBm
reference level and turn the preamplifier on. It’s very helpful
to observe the low- level signals with this settings.
Key access:
Ampiltude > More > Hi-Sensitivity
Ref Offset
Adds an offset value which ranges from - 327.6 dB to +327.6
dB, to the displayed reference level. Reference- level offsets
are only entered by using the numeric keypad. Entering an
offset does not affect the trace or the attenuation value.
Reference- level offsets are used when gain or loss occurs
between a device under test and the analyzer input. Thus,
the signal level measured by the analyzer may be referred to
as the level at the input of an external amplitude- conversion
device. When an amplitude offset is entered, its value
appears on the left side of the display under
Offst (as
opposed to frequency offsets which appear at the bottom of
the display). To eliminate an offset, press
Ref Offset > 0 > dB
.
