3.3.3.6 [Reference offset]
If gain or consumption exists between tested
equipment and spectrum analyzer input, add a
certain offset to reference level to compensate for
generated gain or consumption.
Notes:
This value doesn't change position of curve, only revises
reference level and amplitude reading of marker.
You can use number keys to revise this parameter.
The unit of this offset is dB, not changing with scale and
unit selected.
3.3.3.7 [Reference unit
Pop-up soft menu, used to set units of amplitude of
spectrum analyzer. These units include [dBm], [dBμW],
[dBpW], [dBmV], [dBμV], [W] and [V].
Notes:
1) [dBm]
Select dB relative to 1mW as unit of amplitude.
2) [dBμW]
Select dB relative to 1μW as unit of amplitude.
3) [dBpW]
40
]
Select dB relative to 1pW as unit of amplitude.
4) [dBmV]
Select dB relative to 1mV as unit of amplitude.
5) [dBμV]
Select dB relative to 1 V as unit of amplitude.
6) [W]
Select watt as displayed unit of amplitude.
7) [V]
Select volt as displayed unit of amplitude.
3.3.4
BW/SWP
Set spectrum analyzer's resolution bandwidth, video
bandwidth, sweep time, mode and other related parameters.
3.3.4.1 [Resolution bandwidth Auto Manual]
Set resolution bandwidth to distinguish two signals with
close frequency.
Set resolution bandwidth in auto or manual mode. Underline
under Auto or Manual indicates resolution bandwidth is in
auto mode or manual mode. Press [Resolution bandwidth
Auto Manual] until underline under Auto is highlighted to
make resolution bandwidth in coupling mode, i.e. system
