6-9-1 MODULATING RF SIGNALS WITH DIGITAL SIGNALING FORMATS
Digital Signaling Formats can be used as a modulation source in both RF Generate and
Duplex Generate Operation. With Option 11 installed, optional Digital Signaling
Formats are accessed by selecting the DATA Generator as the Modulation Source.
Additional Formats available with this option include POCSAG and POCSAG Inverted
(POCSAG/).
DATA Modulation Source Block is defined as follows:
1. Modulation Source
Displays selected Modulation Source. Selections
include GEN1 (Audio Generator-1), GEN2 (Audio
Generator-2), DTMF (DTMF Tone Generator),
DATA (DATA Generator), EXT (External
Modulation) and MIC (Microphone Modulation).
2. Modulation Type
Displays selected Modulation Type. Selections
include OFF, AM, FM and PM.
3. Deviation/Modulation Level
Displays selected Deviation in kHz if current Modulation Type (2) is FM with range
from 0.0 to 100 kHz. Displays selected Percent Modulation if current Modulation
Type (2) is AM with range from 0% to 100%. Displays selected Deviation in
radians if current Modulation Type (2) is PM with range from 0 to 10 Radians.
Field is not displayed if Modulation Type (2) is OFF.
4. Format
Displays Format type for Modulation Source (1). Selections available with DATA
include DCS, DCS INV (DCS Inverted), POCSAG and POCSAG INV (POCSAG
Inverted).
Access CONFIG for selecting POCSAG Function, Capcode Range and Data Rate.
Capcode Range values are 1 to 9999999. Start and Stop Capcode are selected.
Activated, the system generates Start Capcode message. Capcode increases by
one and message is sent until Stop Capcode message is generated.
