13-9.2.2 Generate Mode
The analyzer can generate SECURENET voice
patterns when placed in the Generate mode. The
SECURENET signal is encrypted with one of the
hardware algorithms.
Be sure GENERATE is selected in the RF
Control Zone in the upper right section of
display. Move cursor to the Audio Zone and
place the cursor in the "Code:" field. Select Voice
modulation using the
VOICE softkey.
When code Voice is selected in the Audio Zone
(figure 3-13), the analyzer allows audio inputs to
the modulator to be selected from two sources:
External + microphone, or
1 kHz tone
Controls for each modulating input consist of a
switch with values of Off and Continuous. Move
cursor to the appropriate switch field and turn the
modulating input on "~" or off "X" using the
softkeys.
The audio inputs also include a level control for
precisely setting the audio input to the modulator.
Use the keypad or TUNING knob to enter the de-
sired level. The level range varies depending on
whether the bandwidth (in the RF Zone) is set to
narrow or wide.
BW Setting Audio level Range
Narrow 0.00 to 9.95 kHz maximum, in
0.01 kHz increments
Wide 00.0 to 99.5 kHz maximum,
in 0.1 kHz increments
In Generate mode, Deviation control is available
in the Audio Zone consisting of a switch with
values of Off and Continuous, and a level control.
Move cursor to the switch field and turn
deviation on "~" or off "X" using the softkeys.
Use the keypad or TUNING knob to enter the de-
sired deviation. The deviation range varies
depending on whether the bandwidth (in the RF
Zone) is set to narrow or wide.
BW Setting Deviation Range
Narrow 0.00 to 5.00 kHz maximum, in
0.01 kHz increments
Wide 00.0 to 50.0 kHz maximum, in
0.10 kHz increments
The baseband signal of the generated Voice
pattern is available at the MOD OUT connector
on the front panel.
