The
System Info
(Information)
screen
lists the following information:
•
Serial numbers for test set components
•
Software version information
•
Options that are supported and/or enabled on the test set
The
System Info screen
also contains controls to reset the test set to factory default
settings, backup the test set’s system files, and also shows installation options.
Elevation Limit
This value represents the lowest point on the horizon on which
the receiver will try to locate and obtain information from GNSS
satellites.
NOTE
Using satellites near the horizon may degrade performance.
Minimum C/No
(dB-Hz)
This field specifies the minimum Carrier to Noise Ratio (C/No)
for the satellite signals that will be used by the module’s GNSS
receiver.
The C/No is an indication of signal strength ranging from 0 to
50 dBHz.
NOTE
Using satellites with a weak C/No may degrade performance.
Antenna Time
Bias (ns)
This value represents the bias that is used to compensate for
the delay introduced by the antenna, the antenna’s cable, and if
applicable, an in-line splitter or amplifier where absolute
accuracy of PPS is important.
NOTE
The default
Antenna Time Bias
value is 28, which is the optimal value for the
VIAVI qualified antenna. If you are using a different antenna, determine the
optimal bias value by referring to the vendor specifications for the antenna
(and if applicable, splitter or amplifier), then specify the bias value in
nanoseconds.
