S
Sample Rate The number of times per second that an analog signal is measured and
converted to a binary number in order to convert the analog signal to a digital
signal.
Satellite
Downlink
Frequency Within a satellite system, the frequency, either C-Band or Ku-Band, of the signal
transmitted to the receiving dish.
SEQ Sequential
SCPC Single-Channel-Per-Carrier. One video program transmitted per digital
transport stream.
SNMP Simple Network Management Protocol. A widely used network monitoring and
control protocol. Data is passed from SNMP agents, which are hardware and/or
software processes reporting activity in each network device (hub, router,
bridge, etc.) to the workstation console used to oversee the network. The
agents return information contained in a Management Information Base, which
is a data structure that defines what is obtainable from the device and what can
be controlled.
sps Samples per second.
1. A ratio of the number of times that an analog signal is measured and
converted to a binary number to seconds elapsed, expressed as
samples per second.
2. Symbols per second — A ratio of symbols transmitted to seconds
elapsed expressed as symbols per second. Commonly used to express
the speed at which QPSK symbols are transmitted.
Stereo Pair Two audio signals consisting of sound reproduction of the same audio source.
STS-3c Concatenated SONET Synchronous Transport Signal Level 3.
SVC Switched Virtual Circuit. A circuit between two user points in a point -to-point
configuration that is established by ATM signaling stack rather than being a
dedicated circuit.
Symbol In digital transmission, a recognizable electrical state that is associated with a
signal element, which is an electrical signal within a defined period of time.
