Operation
Timing reference
The Timing Reference tab is part of the Acquire control panel. It is only available when an RSA7100 with Option GPS is
connected (units with an IRIG-B connector). This tab allows you to specify the following sources for the timing reference.
Setting
Description
GPS
Speci
fi
es the timing reference for GPS from the
GPS/Antenna
connector on the
instrument front panel.
Click the
icon or select
Setup
>
GNSS/Antenna
from the Main menu bar
of the SignalVu-PC application to access the GNSS and Antenna tabs in the
GNSS/Antenna control panel. From there you can set GNSS source and baud
rate and antenna settings.
PPS
Speci
fi
es the timing reference for PPS (Pulse Per Second) from the
1 PPS
connector on the instrument front panel. The time code of that signal is used to
set the time of SignalVu-PC.
System
Set the timing reference to local PC time. This is the default setting.
IRIG-B AM
When an IRIG-B signal is connected to the instrument using the
IRIG-B
connector
on the front panel, the system
fi
rst checks if an IRIG-B AM signal is present. If
detected, the time code of that signal is used to set the time of SignalVu-PC.
IRIG-B DC
When an IRIG-B signal is connected to the instrument using the
IRIG-B
connector
on the front panel, the system
fi
rst checks if an IRIG-B DC signal is present. If
detected, the time code of that signal is used to set the time of SignalVu-PC.
Valid Time Source
This dish icon indicates the lock status of the selected time source. Green
indicates that the system is locked to the selected time reference. Yellow indicates
that the system is not locked to the selected time reference.
