MP1900A 32 Gbaud PAM4 Solution
Signal Quality Analyzer-R
MP1900A Series
Quick Start Guide
2
Outline
The Signal Quality Analyzer-R MP1900A series features a high-
expandability design with real-time BER measurement using a PAM4
Convert/Decode function, plus sequential PAM4 BER measurements
using an error detector for more efficient inspection of 400GbE
transceivers and devices.
This Quick Start Guide explains use of the MP1900A series to generate
PAM4 signals up to 32 Gbaud, real-time BER measurement using the
32 Gbaud PAM4 Decoder with CTLE G0376A, and sequential PAM4 BER
measurement using the 21G/32Gbit/s SI ED MU195040A.

Equipment setup(1/2)
Select PAM4 Control from Application Selector of
MX183000A software, and click Start.
Click Search Start. The software
searches for equipment, and
displays the equipment currently
connected in the connected
equipment display area.

Equipment setup(2/2)
- Select Jitter, PPG, and ED with unit number from each selection list.
- Select G0375A and G0376A COM port with USB
*Select “None” when Jitter, PPG or ED isn’t used for testing.
- Set External Att value to 6 dB when 6 dB attenuator is used between PPG and
G0375A. (6 dB attenuator is recommended for evaluating SNDR or SNR_ISI.)
