R
Rx —
Receive or receiver or input.
S
SBAS —
Satellite-based augmentation system. A GNSS augmentation system that
improves satellite availability when performing surveys in areas with poor satellite
visibility.
See
GNSS Augmentation.
SETS —
Synchronous Equipment Timing Source.
Slave clock —
PTP clock that obtains precisely synchronized time generated and
distributed by a Grandmaster clock over packet networks (per the IEEE1588 v2 stan-
dard). The TEM Module, when connected to a test instrument and synchronized to
GNSS can provide highly accurate timing and supports measurements of delay
between a PTP master clock and PTP slave clocks.
SONET —
Synchronous optical network.
SQ —
See Signal Quality
.
Sync —
Synchronization.
SyncE —
Synchronized Ethernet.
T
TDEV —
Time Deviation
TEM —
Timing Expansion Module
Term —
See Terminate
Terminate —
An application where the test set is terminating the circuit. In these appli-
cations, the test set sends and receives traffic.
Through —
An application where the test set is used in series with a network circuit to
monitor the traffic on that circuit.
TIE —
Time Interval Error.
Tuning —
The process of synchronizing the frequency of an oscillator to the frequency
of a synchronization source (for example, a received GNSS satellite signal, or an
external 10MHz reference clock). Also referred to as “disciplining” the oscillator.
Tx —
Transmit or transmitter or output.
