RFI
radio frequency interference.
RMA
return material authorization. A form used to return products.
router
A data communications device which examines a packet and routes the packet to an output
port appropriate to the packet destination. On the Internet, a router is a device or, in some
cases, software in a computer that determines the next network point to which a packet
should be forwarded toward its destination. The router is connected to at least two networks
and decides which way to send each information packet based on the router’s current
understanding of the state of the networks it is connected to. A router creates or maintains a
table of the available routes and their conditions and uses this information along with
distance and cost algorithms to determine the best route for a given packet.

RX
receive or receiver.
S
S/N or SNR
signal-to-noise ratio. The ratio, in decibels, of the maximum peak-to-peak voltage of the video
signal, including synchronizing pulse, to the root-mean-square voltage of the noise. Provides
a measure and indication of signal quality.

SA
system amplifier.
SM
status monitor.
SMC
status monitoring and control. The process by which the operation, configuration, and
performance of individual elements in a network or system are monitored and controlled
from a central location.

T
torque
A force that produces rotation or torsion. Usually expressed in lb-ft (pound-feet) or N-m
(Newton-meters). The application of one pound of force on a lever at a point on the lever that
is one foot from the pivot point would produce 1 lb-ft of torque.
