Spectracom SecureSync User Manual

Signature Control: is used to control when the IRIG modulation will be present. This func-
tion allows the modulation to stop under certain conditions;see also "Signature Control"
on page141.
Format: Used to configure the desired IRIG output formatting. The possible values are:
IRIG A
IRIG B
IRIG G
IRIG E
NASA-36
Modulation: Changes the type of output signal modulation. The possible values are:
IRIG DCLS—A TTL-modulated output.
IRIG AM-–An amplitude modulated output. The amplitude of the output is determ-
ined by the value entered in the Amplitude field.
Frequency—The IRIG modulation frequency. This is determined by the con-
figuration of Format and Modulation Type. See also: "IRIG Carrier Frequencies"
on page544.
Coded Expression: Defines the data structure of the IRIG signal, where:
BCD = Binary Coded Decimal
TOY = Time of Year
CF = Control Field
SBS = Straight Binary Seconds
The possible values will vary according to the values of Format and Modulation
Type
Message: The IRIG message of the output.
For IRIG frequency and output specifications, see "IRIG Standards and Specifications" on
page543.
5.2.5.3 STANAG Out [1204-11, -25]
The STANAG Output option card models 1204-11 and 1204-25 provide (2) configurable
STANAG outputs and (1) 1PPS output for the SecureSync platform.
