PAM4 Signal Jitter Tolerance Test using One MP1900A
BER Measurements of 64-Gbaud PAM4 Signals
BER measurements can be performed in real-time using the PAM4 PPG
and ED modules with no need for other external equipment*.
• World-first, all-in-one solution requiring no other external equipment
• Module with built-in clock recovery, equalizer
• Wide-range Emphasis function
• High-sensitivity data input
• Symbol BER evaluation
Jitter Tolerance Test
Testing the DUT receiver input stress tolerance requires BER
measurements under severe conditions using a stressed signal with
added jitter and noise. The all-in-one MP1900A series supports receiver
stress tests for various interface specifications using the Jitter
Modulation Source MU181500B for adding SJ, RJ, BUJ, and SSC
simultaneously, the Jitter Tolerance Test MX183000A-PL001 software,
and the Noise Generator MU195050A for adding CM/DM/White
voltage noise. The MP1900A series provides strong support for high-
quality signals prior to jitter and noise addition, as well as receiver
stressed-signal tolerance tests using high-linearity jitter and noise
addition functions.
