TIE + 1 PPS TE
All connected 1 PPS signals will measure absolute differential TIE relative to the signal
connected to the reference channel. All other signals measure normal TIE relative to the
selected timebase
TE
This performs the same measurement as TIE , but the initial phase offset of each signal
is not compensated for
Diff TIE
All connected signals (including SyncE) will measure differential TIE relative to the signal
connected to the reference channel. See Diff TIE Reference setting
Diff TE
This performs the same measurement as Diff TIE , but the initial phase offset of each
signal is not compensated for
Diff T(I)E reference
Drop-down list for selection of the input channel or internal reference to be used as
reference when TIE Mode is Diff TIE, Diff TE or TIE + 1 PPS TE
G.8271.1 TE Mask Value
Sets the absolute value for the G.8271.1 Max|TE| mask. This is user defined and
configures the Pass/Fail limit for TE measurements when that mask is selected
Note: In all cases, even a delayed start, the measurement is not made until the Start button is pressed.
Timebase
The Timebase page provides the following settings:
Timebase Reference
Internal
Use the internal Rubidium as the reference for measurements
External
Use an external reference for measurements
Auto
Use an external reference if connected to the Freq In connector
and if not use the internal Rubidium reference.
Measurement Start Behavior
Start even if Timebase Reference is not ready
This will start a measurement even if the internal Rubidium
reference is not fully warmed up
Wait till Timebase Reference is ready
The measurement will wait until the reference is fully ready and
warmed
Abort if Timebase Reference is not ready
The measurement will fail if the reference is not ready to proceed
Internal Reference Disciplining Mode
Never
Disable disciplining. The internal Rubidium will remain in free
running mode and will never discipline to GNSS or an external
reference even if available.
Not during measurement
Enable disciplining, but do not use it during measurement
Always
Enable disciplining always, the Rubidium reference will not
discipline if a suitable reference is not available.
Internal Reference Disciplining Source
GNSS
Use internal GNSS receiver.
