demodulating bandwidth can be adjusted if the tested signal is much
wider/narrower than the highlighted area.
In MODU menu, DETECTOR defines the way level meter detects the
signals. This setting can be neglected if the user just want to take a glance of
the level/field strength. Whereas a precise field strength measurement
demands the DETECTOR parameter properly set accroding to different
modulating methods of the signal, or accroding to relevant standards.
(12) Set the data typre of Level Meter. Press MODU button and navigate
to UNIT option. Simply select the appropriate unit. To directly display field
strength, select dBuV/m. In the third page of mode main menu, navigate to
ANT GAIN to tell the machine the gain of the antenna, it would calculate the
field strength automatically. There is also a unit setting in this page, which is
used to determine the unit of the spectrum.
(13) Press AF button to enter audio settings. Parameters are volume,
squelch, level tone, audio bandwidth, telegram tone, audio auto gain, mute,
and so on. Volume can also be adjusted using the knob on the lower left side.
Provided that electronic attenuation or level tone is enabled, by pressing the
knob user can specify whose parameter is to be set.
