The Edit window allows the configuration of the following settings:
Signature Control: Used to control when the IRIG modulation will be present. This function
allows the modulation to stop under certain conditions;see also "Signature Control" on
page141.
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: TTL-modulated output
IRIG AM: 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 configuration of
Format and Modulation Type. See "IRIG Carrier Frequencies" on page544 for details.
Coded Expression: Defines the data structure of the IRIG signal, where:
BCD = Binary Coded Decimal
TOY = Time of Year
