Keysight Technologies recently announced new measurement application software for quickly and accurately measuring and quantifying pulse amplitude modulation with four amplitude levels (PAM-4) signals. The software is used with the Keysight S-Series, 90000A, V-Series, 90000 X- and Z-Series real-time oscilloscope platforms and the 86100D DCA-X Infiniium sampling oscilloscope. The new Keysight N8836A PAM-4 analysis software (for S-Series, 90000A, V-Series, 90000 X- and Z-Series oscilloscopes) and the new N1085A PAM-4 analysis software (for 86100D oscilloscopes) provide comprehensive characterization of electrical PAM-4 signals based on the Optical Internetworking Forum’s Common Electrical Interface (OIF-CEI 4.0) proposed 56G interfaces, and the IEEE 400 Gigabit Ethernet (P802.3bs) standard.
The N8836A and N1085A PAM-4 measurement applications for S-Series, 90000A, V-Series, 90000 X- and Z-Series real-time oscilloscopes and 86100D DCA-X Series sampling oscilloscopes deliver measurements such as: linearity and output voltage measurements including level separation mismatch ratio (RLM); eye width (EW) and eye height (EH); jitter measurements including even-odd jitter and clock random jitter; and differential and common mode return losses performed using a Keysight time domain reflectometer (TDR) or VNA.
The N8836A and N1085A software applications cost $2,500 each.
