Glossary Real-Time Seamless Capture
Real-Time Seamless Capture
The ability to acquire and store an uninterrupted series of time domain samples that represent the behavior
of an RF signal over a long period of time.
Reference Level
The signal level represented by the uppermost graticule line of the analyzer display.
Residual FM (Incidental FM)
Short term displayed frequency instability or jitter due to instability in the analyzer local oscillators. Given
in terms of peak-to-peak frequency deviation and expressed in hertz or percent of the displayed frequency.
Residual Response
A spurious response in the absence of an input signal. (Noise and zero pip are excluded.)
RBW
The RBW determines how well the analyzer can resolve or separate two or more closely spaced signal
components.
Ripple
The Ripple measurement result is displayed in either Watts or Volts. The amplitude units selected on
the Setup > Analysis > Units tab determine whether the measurement is presented in Watts or Volts.
Volts are shown for linear units (for example, volts or amps); Watts are shown for non-linear units (for
example, watts or dBm).
