front-panel key
Keys, typically labeled, and located on the front panel of an instrument.
The key labels identify the function the key activities. Numeric keys and
step keys are two examples of front- panel keys.
full span
A mode of operation in which the analyzer scans the entire frequency
band of an analyzer.
function
The action or purpose which a specific item is intended to perform
or serve. The analyzer contains functions that can be executed via
front-panel key selections, or through programming commands. The
characteristics of these functions are determined by the firmware in the
instrument. In some cases, a DLP (downloadable program) execution
of a function allows you to execute the function from front-panel key
selections.
gain compression
The signal level at the input mixer of an analyzer where the displayed
amplitude of the signal is a specific number of
dB
too low due just to
mixer saturation. The signal level is generally specified for 1
dB
or 0.5
dB
compression and is usually between -3
dBm
and
-
10
dBm.
gated measurement
See time-gate.
hard copy
Information or data printed onto paper as opposed to its being stored on
disk or in the instrument’s memory.
harmonic distortion
Undesired frequency components added to signals as a result of nonlinear
behavior of the device (for example, a mixer or an amplifier) through
which signals pass. These unwanted components are harmonically related
to the original signal.
harmonic mixing
The utilization of local oscillator harmonics generated in a mixer to extend
the tuning range of an analyzer beyond the range achievable using just
the local oscillator fundamental. The mathematical algorithm is:
FIN =
FLO
