11. Using the results group and category drop-
down menus, change the right results
display to the following:
• Satellites/Sky Plot: Displays the
satellites that are identified using
the GNSS receiver. Ensure at least 4
satellites are "Used". Otherwise,
relocate antenna to a less
obstructed location.
• Satellites/Signal Strength: Displays
the signal strength for each
identified satellite. Ensure signal
strength of used satellites exceeds
Minimum C/No setting. Otherwise,
reduce Minimum C/No setting.
• GNSS/Status: Displays general
information concerning the GNSS
Satellites. Ensure that Status
progresses from "No Lock" to
"Locked" to "Fixed Position" during
the survey. Ensure that Timing
Mode Status progresses from
"Survey" to "Survey Done".
Note: If you are using a T-BERD 5800v2
and Timing Module (C5TEM-R), the
Summary LED and Summary/Status
results display will remain red until the
rubidium oscillator is tuned.
12. Once the survey is done (and the oscillator
is tuned if using TEM), you are ready to
perform timing tests using the attached
antenna, including:
• One-way delay measurement
• IEEE 1588 Precision Time Protocol
(PTP) Time Error, Asymmetry, and
Packet Delay Variation (PDV)
measurements.
• Wander analysis
• Timing and 1PPS Analysis
