BSG

Aeroflex promotes the 600MHz band width the digital wide band signal measuring instrument Wireless and the satellite communication technology is now the communication domain most has the prospect and rousing, the digital wide band test survey plan is promotes this technical the key. Aeroflex is satisfies the fast development the communication domain wide band test request, has provided now the maximum band width, the biggest memory depth measuring instrument, from the signal generating device, the channel simulator to the data acquisition record and the analysis system, for the design, the research and development, debugged various advanced communication and the entertainment product has provided the basic testing tool.

The Aeroflex wide band signal and the environment simulation generator (BSG) the series provides RF and the baseband supply oscillator which now the most wide band affable greatest depth saves. BSG unified in the depth memory, the high speed free profile generator and the wide band radio frequency the frequency changer, and provides the function formidable signal to have software. BSG may provide the 500MHz band width, the memory may amount to for 10 seconds. Vector signal imitation software (VSS) produces uses in the commercial wireless standard signal document, similarly also may produce nPSK, nQAM, nFSK, MSK, CW, the audio frequency combs with the saw notch noise signal. Regarding any general type signal, may add the threshold in the time domain and arise suddenly the control, carries on the jump in the frequency range. The Aeroflex wide band recording instrument or other recording instruments record the signal, may join and with the digital generator signal closed circuit, returns by BSG puts. The unwanted signal may join to the signal in, including: The thermal noise, the phase noise, the pass band scope and the phase wonderfully change.

The Aeroflex wide band channel simulator may real-time join the unwanted signal actual for the input signal, the simulation transmits the channel disturbance. The Aeroflex channel simulator has succeeded applies in many satellites project, uses in the simulated signal round-trip way, may before the launch carries on the comprehensive test to the satellite and the ground station. May provide the unwanted signal includes:

The Aeroflex wide band signal analysing and the recording instrument (BSA) the series provides the radio frequency/baseband signal analysing which now the most wide band affable most depth saves. BSA unified under wide band RF the frequency changer, the wide band high dynamirange ADC transformation and the greatest depth high speed memory, union function formidable DSP signal analysing software. BSA has 600 MHz band width, the signal saves may amount to for 10 seconds. DSP software and to saves including the real-time input signal analysis in BSA the signal analysis. The digitization gains and processes uses in to realize the high-accuracy survey and the duplicated test. The memory signal also may return by the Aeroflex wide band signal generating device puts. The nimble data display includes: Frequency, time and modulation parameter (all parameters and data position). Tests software to include: Digital spectrometer, various channels power and power ratio, PSK and QAM demodulation and analysis (including EVM, view, sample rate, carrier frequency and sample), signal statistics and other signal demodulations.

Aeroflex has provided the different band width multiple options, may apply in each kind of application domain. Through the choice different on/under frequency changer, the signal carrier may reach 40GHz. The wide band, the depth memory and the big dynamirange cause it to become the wide band satellite communication, the wide band wireless network communication, the radar test, the frequency agility wireless communication, the multichannel signal imitation and the analysis, the phase noise simulation and so on the basic tool.

Frequency agility simulation and analysis: The Aeroflex wide band test facility permission carries on the fast frequency jump in its band width scope, regardless of is the signal generating device or the signal recording analyzer, the jump speed may achieve 5.00, million times of/seconds, analyze software to be possible to provide the time domain profile, the jump frequency time distribution, and may alone observe the single jump signal the frequency spectrum characteristic and so on.
