Used as the electrical signaling devices in the above mentioned 28 GBaud DP-QPSK systems, 28-32 Gb/s SERDES are accurately characterized for jitter with a two channel 50 GHz LabMaster 10 Zi system. These oscilloscopes offer far more bandwidth with the ability to capture beyond the third harmonic of 28 Gb/s NRZ signals at a price point of $365,900, only one third higher than competitive 32 or 33 GHz oscilloscopes. The customer can also purchase up to 60 GHz for this application and capture the fourth harmonic of these signals.
Research is already progressing on >56 GBaud (224 Gb/s) DP-QPSK and 16-QAM optical coherent modulation systems. LabMaster 10 Zi can be configured as a 2 to 4 channel 60 GHz system to allow research at the highest possible symbol rates, approaching 125 GBaud (500 Gb/s) for DP-QPSK or 1 Tb/s for 16-QAM. The industry-leading 160 GS/s sample rate will be highly appreciated for acquisition of high speed phase-modulated signals. List prices for 60 GHz LabMaster 10 Zi systems start at $411,900.
Lastly, optical transmission developments beyond 1 Tb/s will likely make use of lower data transmission rates but mode or frequency domain multiplexing, such as MIMO or OFDM, will require more than the four acquisition channels commonly provided in conventional oscilloscopes. LabMaster 10 Zi modular oscilloscopes provide up to 20 channels at 36 GHz or 10 channels at 60 GHz, thus making possible the development of advanced optical communication systems that would otherwise not be feasible.
