SIGLENT's latest VNA release is the SVA1015X, which is based on the company's SSA3000X series of
superheterodyne spectrum analyzers.
The
superheterodyne receiver is one of the most successful forms of radio used in electronics and information systems.
In this paper, the
superheterodyne receiver of a commercially available RFIC is used to achieve a longer range than that of a superregenerative receiver.
The receiver is based on the double
superheterodyne concept (Fig.
Different from conventional
superheterodyne receivers, the coastal UHF radar receiver directly samples the echoes in RF (radio frequency) stage and both the frequency downconversion and signal demodulation are performed in digital domain and thus the receiver is called "full-digital receiver" [7].
The DCR is able to do away with the surface acoustic wave (SAW) filter which is typical of
superheterodyne receivers, thus reducing size, cost, and complexity.
A
superheterodyne spectroscopy (33,34) was developed with the intermediate frequency ([[omega].sub.TF]) of 25 MHz, which is provided by the local synthesizer.
To ensure correct navigation, Mackay purchased a nine-valve
superheterodyne wireless receiving set, and carried it for the whole trip.
H.: 9-GHz Complex Permittivity Measurements of High-Loss Liquids Using a VariableLength Reflection Cavity and a DualChannel, Double
Superheterodyne Signal Processing System.
Taking the electrodynamics and the lasers in turn, he considers such topics as high-current free electron lasers as a historical relic of the Star Wars epoch, hierarchic systems with fast rotating phases, whether hierarchic oscillations and waves are the foundation of the world, the weak-signal theory of parametrical (ordinary) free electron lasers, and two-stream
superheterodyne free electron lasers.
