Format: Once a Format Group has been selected, one or more Format
fields may appear, allowing you to select one or more time code Formats.
For more information on time code formats, see "Time Code Data Formats"
on page560.
The choice of format group determines t he format choices available
in the Format 1, Format 2 and Format 3 fields.
Format 1: Selects either the first of up to three, or the only
format message to be output. See "Time Code Data Formats"
on page560 for a description of available formats.
Format 2: Selects the second consecutive format message to
be outputted. Select “None” if only one output format is
desired. See "Time Code Data Formats" on page560 for a
description of available formats.
Format 3: Selects the third consecutive format message to be
outputted. Select “None” if only one output format is desired.
See "Time Code Data Formats" on page560 for a description of
available formats.
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 page183.
Output Mode: This field determines when the output data will be provided.
The available Mode selections are as follows:
Broadcast: The format messages are automatically sent out on
authorized condition (Signature control), every second a message is
generated in sync with the 1PPS.
Request (On-time): A format message is generated in sync with 1PPS
after the configured request character has been received.
Request (Immediate): A format message is generated as soon as the
request character is received. As this selection does not correlate the
output data to the on-time point for the message, in Data Formats
that do not provide sub-second information (such as Formats 0 and 1
whereas Format 2 provides sub-second information), it should be
noted that the output data can be provided immediately, but a time
error could occur when using the on-time point of the message in
addition to the data for timing applications.
