Maximum Input Power- The maximum RF signal input level that is non-destructive to the operation of the equipment.

MHz– one megahertz equals 1,000,000 Hz.

Non-Blocking Matrix- A matrix switch in which an input or an output may be connected to multiple inputs or outputs. (See Fan-In and Fan-out for more detailed description)

Non-Inverting– Typically the output of a mixer in which the Local Oscillator frequency is below the input frequency and the output is the sum of the two frequencies

Operating Frequency-The lower and upper operational frequency limits as specified on the product specification sheet.

Output Return Loss– The standing wave ratio measured at the output port of an RF combiner with all output ports properly terminated, expressed as dB. (also referred to as Output VSWR, expressed in a ratio).
