Keysight Technologies, Inc. introduces new measurement software, PAM-4 (pulse amplitude modulation with four amplitude levels), for real-time oscilloscopes. This software was designed for include the V-series, Z-series and S-series. These three series’ offer the lowest noise floors for wide bandwidth in the industry for real-time oscilloscopes, according to the company.
Most high-speed and mobile applications rely upon NRZ (non-return-to-zero) encoding, however, NRZ will not work in 56-GBit/s environments. To fix this problem, the modulation technique can be changed from NRZ to pulse amplitude modulation.
“Our customers face many new design and measurement challenges as they make the switch from NRZ to PAM-4 signaling. By delivering both analysis and debug capabilities for PAM-4 signals, our latest PAM-4 analysis software for our real-time oscilloscopes helps engineers address these challenges and quickly get their designs to market,” Dave Cipriani, vice president of Keysight’s oscilloscope division, said.
The PAM-4 software allows engineers to accurately and quickly perform measurements. The software offers the following measurements: eye wide, eye height, eye skew, level amplitude, level noise, level skew, and amplitude level linearity.
