1. Q-ROUTE – Provides Internal Signal Path Redundancy by Automatically Re-routing Around a Failed Signal Path (Example) Q-SENSE – Provides External Signal Path Redundancy by Automatic Switching of Back-up Input Signals (Example) RF Router– A switch used to monitor multiple RF signals inputs (one at a time) to a single output, for use with test equipment such as a spectrum analyzer RoHS-Restriction of Hazardous Substances.. Signal To Noise Ratio– (S/N) - The ratio of desired signal level to the undesired noise level, expressed in dB. (Sometimes expressed as SNR). Splitter- A device used to split (divide) a common RF signal to multiple outputs while maintaining impedance matching. (See Active and Passive).

2. Signal Strength– The level of an RF signal measured in volts (V), millivolts (mV), microvolts (µV), dBmV or dBm.

3. SPDT-single-pole double-throw switch

Terminator– A resistive device connected to unused ports on splitters and combiners to reduce unwanted signal reflections, ingress or egress problems due to impedance mismatches

Unity Gain- A design characteristic to cancel losses inherent in electronic equipment, typically using active amplifier components.

Up Converter– A device used to convert a signal of lower frequency to a signal of higher frequency.

VSWR- Voltage standing wave ratio, frequently referred to as return loss, it is the ratio of signal loss due to reflected signals caused by impedance mismatches.
