At the RN, the downlink signal is combined with the coming P2P light from BS_1 by a 33/66-GHz optical interleaver (IL) to realize single sideband
transmission for the two signals.
There is the hiss of the burner, and the single sideband
radio is on.
The AIP method even suppresses the feed through on single sideband
signals, and consequently the intelligence on the signal can be detected while the system is deriving the bearing angles.
5120A Combines Ease-of-use, Cost Efficiency and Accuracy for Single Sideband
(SSB) Phase Noise and ADEV Measurements
Detailed digital modulation analysis is not possible, but the unit does perform amplitude modulation, frequency modulation, and single sideband
(AM/FM/SSB) demodulation and has the capability to identify common signal types by their bandwidth and spectrum skirt shape as an aid to determining the sources of interference.
(SSB) phase noise performance is -78 dBc/Hz and -108 dBc/Hz at 10 kHz and 100 kHz offsets, respectively.
A sample of the radar LO is used with the synthesized signals in phase-locked loops to generate the desired Doppler shifted clutter and target are used rather than single sideband
modultion of the radar transmitted signal to reduce the spurious signals in the output.
The RFT5600 device includes a quadrature baseband-to-IF upconverter, a programmable PLL for generating the Tx IF frequency, Tx IF voltage controlled oscillator (VCO), single sideband
upconversion from IF to RF, one cellular and two Personal Communications Service (PCS) driver amplifiers, and Tx power control through an 85 dB variable gain amplifier (VGA).
phase noise is specified in dBc/Hz at a given frequency offset from the carrier.
Both HP E5500 systems include a low-noise modular measurement system (MMS) baseband test set that measures the single sideband
phase noise of high-frequency oscillators using the phase detector with reference-source method.
Mini-Circuits measures single sideband
phase noise for characterizing short term stability of a signal, since small FM deviations are difficult to measure.
Many customers who had tried other systems, including both cellular and single sideband
, took this opportunity to express their frustration with the lack of reliability and general problems with data collection they experienced with those methods.
