SCREEN FEATURE FUNCTION
Level Used to select the signal generator output level.
The Generator Output Level Units can be toggled between dBm and
μV.
Select: Ant -90 to -30 dBm in 1 dB increments
T/R -120 to -50 dBm in 1 dB increments
SWR -65 to -5 dBm in 1 dB increments
Select: Ant 7.07 to 7071.03 μV in 1 dB increments
T/R 0.22 to 707.11 μ V in 1 dB increments
SWR 125.74 to 125743.3 μV in 1 dB increments
Ext Attn dB Used to select the external attenuation on the output connector.
Select: 0 to 30 dB in 1 dB increments
Modulation Type Used to select the modulation type.
Select: AM, FM or Off
Modulator Used to change functionality of the modulation source fields.
Press F1 “ENTER” Key to toggle between Analog (CTCSS), DCS and
DTMF modulation source fields.
NOTE: The total combined modulation from all sources in each
Modulatorframe cannot exceed 100% for AM or 100 kHz for
FM.
If the modulation level of a selection source is set to a value
that would cause the total modulation to exceed the
modulation limit, the value of the unselected sources are
lowered automatically.
Analog (CTCSS) Modulation Source Fields
Gen 1 Used to select internal modulation.
Select: On or Off
AM:
Freq 0 to 20000 Hz in 1 Hz increments
%Mod 0% to 100% in 0.1% increments
FM:
Freq 0 to 20000 Hz in 1 Hz increments
Dev kHz 0 to 100 kHz in 0.01 kHz increments
