The Signal Quality Analyzer MP1800A is a plug-in modular Bit Error Rate Tester (BERT) supporting measurement of multi-channel wideband interfaces up to 64 Gbit/s. The newly developed G0375A and G0376A are remote heads for addition to the MP1800A series 32G PPG/ED to extend measurement support for PAM4 measurements using NRZ measuring instruments.
Combining the G0375A with the 28G/32Gbit/s PPG MU183020A converts two 32 Gbit/s NRZ signals to output a high-amplitude PAM4 signal of 4.4 Vp-p (differential, max.). Additionally, the 3ch PPG synchronization function for independent control of the PAM4 signal 3Eye amplitudes enables high-reproducibility evaluation of optical modulators without using an external driver amplifier.
With built-in PAM4 decode and CTLE functions, the G0376A supports measurement of PAM4 decoded binary signals using the 28G/32Gbit/s High Sensitivity ED MU183040B. In addition, combination with the CTLE function supports high-efficiency, input-sensitivity performance tests.
