Modulation Distortion For E5081A Up To 20 GHz
S960704B
-
The Keysight S960704B modulation distortion software application enables fast and accurate active device modulation distortion characterization under modulated signal conditions up to 20 GHz. The wide dynamic range and vector error correction of the ENA-X yield an extremely low residual EVM of the test setup, delivering a complete picture of your device’s signal distortion performance without test system interference. S960704B software measures EVM, NPR, ACPR, and decomposes linear and nonlinear signals by spectrally correlating input and output spectrum without needing to demodulate. Integration with the ENA-X measurement flexibility enables quick modulated signal distortion measurements along with traditional VNA tests.

Digitizer
The Keysight M8296A is a four-channel, high-speed electrical digitizer module for the AXIe platform. It can synchronously sample up to four incident waveforms and is ideally suited to digitize the output signals from a dual-polarization coherent receiver. Keysight's vector signal analyzer and optical modulation analyzer software serves as the M8296A's user interface and enables a multitude of test and measurement tasks such as spectral analysis and digital demodulation for the analysis of signal quality metrics like error-vector magnitude. Furthermore, the sampled waveform can be stored and processed with the user's own tools (e.g. using Matlab). The modular approach allows users to combine the M8296A high-speed digitizer with other modules in one mainframe such as the M8292A modular optical modulation analyzer and the M8196A 92 GSa/s arbitrary waveform generator.

40Gb/s DPSK Receivers
-
Targeting for the next-generation 40Gb/s system based on advanced optical differential phase shift keying (DPSK) demodulation, Optoplex’s 40Gb/s Integrated DPSK Receiver (DPSK Rx) demodulates an incoming DPSK optical signal into a pair of differentially (amplitude) modulated RF outputs at data rate up to 43Gb/s in a compact package. Phase modulated optical signals offer much better dispersion performance compared with traditional amplitude modulated counterparts because the carrier light stays on all the time so that the intensity-dependent nonlinear effects in the transmission link are avoided, resulting in longer transmission distances.
