Operating the TSG-3800
Setting Up Input Reference Controls
Note: Fault limits and modes are independent for each Input
module and may be set differently.
You use the Input command to display and set the fault limits for the input signal; the
command syntax is described in
Displaying Input Signal Fault Limits
To display the Input Signal fault mode assignment, error count, and clear count,
type:
INPUT {input} AIS|BPV|CRC|LOS|OOF
A typical display shows:
TSG->INPUT LOS
Module
Inp1.1
Inp2.1
Inp3.1
Inp4.1
TSG->
LMT is the current value of the 1-second alarm thresholds. MODE is the current
fault mode. INP1.1 through INP4.1 list the current 1-second error and clear count for
each channel.
Assigning Input Fault Modes
The operator can assign an individual fault mode for each type of signal fault. Fault
modes are: Fail, Alarm, Report, Ignore. Refer to
94, for explanations.

Displaying Phase Measurements

The TSG-3800 measures the phase between each input and each clock. You can
display:
The most recent phase measurement for all inputs
Up to the last one hundred 1-second interval phase readings between the clocks
and a specified input
Up to the last one thousand 100-second average phase readings (27 hours)
between the clocks and a specified input
Phase data can indicate the general health of equipment and can be used for
troubleshooting. For instance:
