DCA1065 Sampling Oscilloscope
65GHz sampling oscilloscope for 1.6T optical transceiver testing
Semight DCA1065 Sampling Oscilloscope — Fully meets the testing needs of the 1.6T optical module!
The 200Gbps per lane data rate not only achieves higher bandwidth but also significantly contributes to power consumption reduction. On the other hand, evaluating such high-speed signals requires extremely advanced measurement techniques. Semight has developed the "DCA1065," a wideband sampling oscilloscope that employs a newly designed ASIC compatible with 200Gbps per lane, addressing the challenges of high-speed signal measurement. With the System Impulse Response Correction (SIRC) function, it can flexibly respond to signal measurement requirements under various data rate conditions. Additionally, it supports up to 64 taps in the feedforward equalizer (FFE) for TDECQ, effectively reducing inter-symbol interference (ISI).

Detailed information
-
■ Multi-Port Integrated Design **Compact design (half-rack width)** significantly saves installation space Supports 1/2/4 channel configurations, enabling flexible system construction.
-
■ TDECQ (Transmitter and Dispersion Eye Closure Quaternary) Measurement TDECQ is measured based on two vertical histograms on the eye diagram. These histograms are ideally centered at 0.45 UI and 0.55 UI, maintaining a spacing of 0.1 UI. The width of each histogram window is 0.04 UI, covering all modulation levels. The point of the measurement is to fine-tune the position of the histograms to obtain the minimum TDECQ value. The figure below shows an image of the TDECQ measurement window.
-
■ OMA (Outer Optical Modulation Amplitude) Measurement OMA (Outer Optical Modulation Amplitude) is defined as the difference in optical power levels P₃ and P₀ at the center of two UIs within a **specified pattern (seven consecutive "3"s and six "0"s)**. The calculation formula is as follows:
