Unit Sync. Control

Supports PAM4 Jitter Tolerance test using just one unit. A measurement system to help cut measurement time is configured easily by combining the Jitter/Noise

Addition function, built-in Clock Recovery function, and Jitter Tolerance

MX183000A-PL001 software.

Jitter Tolerance Measurement Function

Sine-Wave Jitter (SJ) Random Jitter (RJ) CM/DM Noise White Noise

Uncorrectable Codeword and FEC Symbol Errors can be measured and displayed on one screen in real-time simultaneously with bit error measurements. Measurement of jitter tolerance and FEC Symbol Error per codeword distribution based on correctable/uncorrectable FEC is supported (MU196040B-042).

Both bit error and FEC Symbol Errors are measured at high speed.

Measurement Functions

When the DUT has a built-in bit error counter, combination with the MP1900A PPG makes it easy to configure a highly cost-effective Jitter Tolerance measurement environment.

Jitter Tolerance Measurement using DUT BER Counter

(MX183000A-PL001 Jitter tolerance software) (MX183000A-PL031 DUT Error Counts Import)

FEC can be evaluated by combining FEC pattern generation with error insertion, and reading the DUT bit error count.

Multilane FEC Evaluation

Evaluate Jitter Tolerance, etc., using captured error count
