Glossary
Spurious Response
A response to a analyzer wherein the displayed frequency is not related to the input frequency.
Time Measurement
This is the time in seconds relative to the time reference point in the first acquisition record in the data set.
Time Reference
The point in time during the acquisition record used as the zero point for counting time. The time reference
can be set to either the start of the acquisition record or the trigger point.
Trace
As used in this help, trace refers to the displayed signal. The displayed signal can be a processed version of
the input signal (for example, it may be averaged.) The trace is a result or output.
Vector Signal Analyzer
Like a spectrum analyzer, a device for determining the frequency components of a signal. However, unlike
a standard spectrum analyzer, the vector signal analyzer is optimized for analyzing digitally modulated
RF signals.
Vertical Scale Factor, Vertical Display Factor
The number of dB, volts, etc., represented by one vertical division of a spectrum analyzer display screen.
