Get peace of mind only Keysight can offer. With KeysightCare Assured and manufacturer calibration.

*If the unit is not yet calibrated (see listing), a calibration is required to purchase a KeysightCare plan.

• Expands data rate of J-BERT M8020A up to 32 Gb/s and J-BERT N4903B pattern generator up to 28.4 Gb/s
• Adjustable positive and negative de-emphasis for up to 8 taps, optional
• Internal superposition of interference for common-mode and differential mode
• Transparent to jitter generated by J-BERT M8020A and N4903B
• Clock/2 jitter can be added
• Electrical idle
• Control from J-BERT M8020A and N4903B user interface via USB

R&D and test engineers who need to characterize serial interfaces of up to 32.0 Gb/s can use the M8061A 2:1 Multiplexer with optional de-emphasis to extend the rate of J-BERT M8020A and J-BERT N4903B pattern generator. For the most accurate receiver characterization results, the M8061A provides four calibrated de-emphasis taps, which can be extended to eight taps, built-in superposition of level interference and Clock/2 jitter injection. The M8061A is a 2-slot AXIe module that can be controlled via USB from the user interface of J-BERT M8020A as well as N4903B.

Application examples for M8061A:

• Optical transceivers such as 100GBASE-LR4, -SR4 and -ER4, 32G Fibre Channel
• SERDES and chip-to-chip interfaces, such as OIF CEI
• Backplanes, cables, such as 100GBASE-KR4, -CR4

Emulate transmitter de-emphasis with up to 8 taps

Many multi gigabit serial interfaces use transmitter de-emphasis to compensate for electrical signal degradations caused by printed circuit boards or cables between the transmitter and the receiver ports. R&D and test engineers who need to characterize receiver ports under realistic and worst case conditions require a pattern generator that allows to accurately emulate transmitter de-emphasis with adjustable multi-tap de-emphasis levels. The M8061A can be used in combination with J-BERT M8020A as shown below.

De-embed signal degradations caused by the test set up and fixtures using de-emphasis

Minimizing the influence of the test environment is a challenge especially if bit rates exceed 20 Gb/s. To de-embed the signal degradations caused by cables, test fixtures, adapters, etc, the de-emphasis technique is commonly used. M8061A is the only instrument that offers up to 8 tap de-emphasis up to 32 Gb/s, allowing compensation of signal degradations in very fine steps.
