UNCTION
LBWS (Limited Band Width Sweep) is a function that sweeps a limited segment of the Spectrum Scope span
without changing the span (bandwidth). As the sweep segment becomes narrower, the speed becomes faster,
and the accuracy and resolution become enhanced.
The bandwidth can be set to 50 %, 30 %, or 10 % of the full span. The sweep speed will increase as follows:
50 %: about 2 times faster, 30 %: about 3 times faster, 10 %: about 10 times faster

Advice :Please note that the LBWS feature can not
be used in the FIX mode. Please use LBWS only in
the CTR mode.
While LBWS is engaged, it is not possible to switch
to the dual display mode.
In the case of the Contest version, the [ RX
] switch to
the left of the [ CLAR/VFO-B
] knob will, when pushed,
cause both the VFO itself and the Spectrum Scope
display to change to VFO-B. Additionally, when the
optional
RXU-9000 Dual Receive Unit is installed,
you may use the [ 4/7
](
A/B
) key to make this change,
just like on the MP version.
