About 1PPS wander analysis
If your TEM Module optioned to do so, you can place it into 1PPS Analysis mode, then
use it to perform highly accurate wander analysis of a 1PPS signal by measuring the
Time Interval Error (TIE) and calculating the Maximum Time Interval Error/Time Devia-
tion (MTIE/TDEV) on the TEM itself. You can also export TIE data for analysis on a PC
using optional O.172 MTIE/TDEV Offline Analysis software.
Before performing 1PPS wander analysis using the TEM, you must turn the oscillator
on and wait for it to warm up. For details, see
“Turning on the Rubidium Oscillator” on
.
Signal Input
lists the connections required to provide the external timing reference signal
and analyzed signal to the TEM Module when performing 1PPS wander analysis using
the TEM Module in 1 PPS Analysis mode.
LEDs and test results
When you put the TEM Module into 1 PPS Analysis mode, supporting results are avail-
able in the 1 PPS Analysis result category. The LED panel (shown in
