Xu Zhengping, Deutsche Technologies' Greater China Market Development Manager, said that due to the higher phase noise of the 5G, it will cause the carrier and the carrier to easily interact with each other, resulting in a signal quality degradation caused by the signal generator. Therefore, the 5G signal generator pair Phase noise requirements become quite strict, and this new PXIe microwave signal generator in the low phase noise on the great breakthrough in the 10KHz offset reached less than -115 dBc / Hz, and Germany is the high pointer of the PSG (E8257D) is not Points up and down.
And the output power, compared to the current market competing products can only reach +12 ~ 13dBm, the output amplitude of the generator range of up to +19 dBm. Germany is also used to produce the generator in the 28GHz band 800MHz pre- 5G waveform signal, and achieve 1% error vector magnitude (EVM).
In addition, the new PXIe signal generator can be expanded and upgraded. Engineers can increase the number of channels in the vector or analog configuration.Users can also follow the evolution of the signal standard, the frequency, bandwidth and other performance features through the external IQ input, modulation bandwidth can be further increased to 2GHz.
Xu Zhengping further said that the new PXIe signal generator has three major features, the first is a very high performance, including high output power, low phase noise (Phased Noise), the frequency switching speed is very fast, the second is the frequency of flexibility High, whether it is 14, 20, 31.8, 44GHz and other bandwidth, can be freely configured. The third is the future of software and hardware upgrades.
The new Keysight M9383A PXIe analog and vector signal generator, now widely used by 5G development teams operating in sub-6GHz, 28GHz and 39GHz bands, enables engineers to interface with PXIe signals through Keysight Signal Studio or Keysight SystemVue software Generator to provide 5GTF compliant waveforms and 5G candidate waveforms such as 8 × 100 MHz OFDM subcarriers (constant current) available to engineers for emerging wireless, 5G new radio (5G NR) And aerospace and defense applications, resulting in custom waveforms.
