The Edit window allows the configuration of the following settings:
Signature Control: Is used to control when the IRIG modulation will be present.
This function allows the modulation to stop under certain conditions;see also "Sig-
nature Control" on page161.
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
determined 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 Fre-
quencies" on page546.
Coded Expression: Defines the data structure of the IRIG signal, where:
BCD = Binary Coded Decimal
TOY = Time of Year
CF = Control Field
