1.6T Sampling Oscilloscope (DCA1065)
In the field of optical communications, the 200Gbps/lane rate provides higher communication bandwidth and significantly reduces power consumption, but at the same time brings enormous challenges to test and measurement. For 200Gbps/lane signals, Semight Instruments redesigned a dedicated ASIC and launched the new broadband optical sampling oscilloscope DCA1065.; DCA1065 supports physical-layer performance testing of 400G/800G/1.6T bps optical modules, optical cables, and related components in fields such as data centers, core/metro networks, 4G/5G mobile backhaul, and 5G mobile fronthaul.; DCA1065 is backward compatible with some functions of DCA6201 [1]; users can run the DCA1065 companion software on a PC and achieve efficient automated testing through remote control via the LAN/USB interface. This product can simultaneously support eye diagram testing of 4 optical signals, supports testing single-mode (1200~1600nm wavelength) 53~56GBd and 106~112GBd[2] PAM4 signals, and features algorithms such as extinction ratio correction, dark current self-calibration, and system frequency response correction (System Impulse Response Correction), satisfying the testing of signals at different rates and ensuring the accuracy of test results. In addition, DCA1065 supports a TDECQ feed forward equalizer (Feed Forward Equalizer, FFE) of up to 64Taps for inter-symbol interference (Inter Symbol interference, ISI) elimination.; [1] Compatible with 50GBd PAM4 testing in single-mode PatternLock mode.; [2] Supports typical commonly used rates.
