6.13 TIC Measurements
The 4380A is capable of providing up to 4 TIC measurements on a single 4393A Card. The measurement
average (Port 2100) is 10 seconds by default. The raw measurements are output on each active channel
(Port 2101).
Raw Measurements (Port 2101):
o
All of the active channels should have a measurement once per second. If not the 1 PPS input
from the device under test is missing.
o
Inactive inputs ports (channels) will not report measurements.
Average Measurements (Port 2100):
o
The number of samples (nn event average) should match the
settings ptd_port
value. If not:
The cable from the device under test was disconnected/reconnected during the
measurement process.
4380A outputs were enabled during the measurement period.
1PPS from the source was interrupted during the measurement process.
The 1PPS signal is missing
Make sure the interval is set properly, the unit will not report the measurement results and
the average for that period until the period expires (i.e. 300 seconds = 5 minutes).

2.

software_update
command.
3.
The system was power cycled or rebooted after the file was loaded and prior to launching the
software_update routine.
6.15 Configuration Not Readable
The internal bus used to communicate with the plug in modules and power supplies to determine their type
and serial number is the I2C bus. If this alarm occurs the system should continue to operate correctly, but
