GM Offset <Integer>
Default: 0
Offset to compensate user cable delay for PPS input (in
picoseconds). When Align PPS is enabled the PPS out-

might want to compensate this delay.
3.7110.2
Priority1
<Integer>
Default: 128

Accuracy
<Enum> Default:
Unknown
It announces the expected accuracy provided by the
external reference. It shall be conservatively estimated
based on the type of time source (e.g., Atomic Clock <=

day (ToD).

Info/Overview
The GM timing source provides its own overview panel where the user can easily audit the

Figure 5-19:
Overview tab for GM timing source.
It basically offers a readback of the configuration value (Source Type, Source Rank, Align
PPS and PPS Mandatory) as detailed
"Configuration" on the previous page
, along with an
user friendly Message that summarize the state of the GM internal state machine and a
Detected value that reports the situation with the external reference inputs signals. Finally,
