The Edit window allows the configuration of the following settings:
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136.
Format: Used to configure the desired IRIG output formatting. The available choices are:
IRIG A
IRIG B
IRIG G
IRIG E
NASA-36
Modulation: Changes the type of output signal modulation. The available choices 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524.
Coded Expression: Defines the data structure of the IRIG signal, where:
BCD = Binary Coded Decimal
TOY = Time of Year
