• M8051A high-performance BERT generator-analyzer 8/16 Gb/s.

• M8061A multiplexer 2:1 with de-emphasis 32 Gb/s.

• M8062A 32Gb/s Front-end for J-BERT M8020A High-Performance BERT

• In addition to above J-BERT modules, it also supports M8195A and M8196A Arbitrary Waveform Generator modules. Details of these modules can be found at www.keysight.com/find/m8195a and

www.keysight.com/find/m8196a

M8020A being a modular product includes different sets of modules which are hosted in an AXI chassis. Each module and its features have their own license. You need to install these options in your instrument in order to use the modules or features. For details, refer to the chapter Licenses on page 613. However, if you have ordered M8020A-BU1, no license is required.

The M8041A module must be installed in slots 1 through 3 in the AXIe chassis unless the M9536A AXIe Embedded Controller is installed. The following configurations are possible in an M9505A 5-slot chassis:

• 1 or 2-channel, 16 Gb/s - (1) M8041A

• 3 or 4-channel, 16 Gb/s - (1) M8041A + (1) M8051A

• 1-channel, 32 Gb/s (Pattern Generator only) - (1) M8041A + (1) M8061A

• 1-channel, 32 Gb/s (Pattern Generator only or full BERT) - (1) M8041A + (1) M8062A

• M8195A/M8196A module can more or less arbitrarily be added into the 5 slot module

Additionally, the M8061A, M8062A and M8195A/M8196A modules can be installed and operated in a 2 slot frame.

In case an AWG module (M8195A/M8196A) is used in a combined system with M8020A modules, ensure that the AWG modules should be always be mounted in a slot number higher that M8020A modules in the AXIe chassis. In other words, an AWG module always has to mounted last in the chassis.

Error Add Input

Every rising edge at the input generates a single error in the output data stream by flipping a single bit. The maximum repetition rate is data rate divided by 4 times the vector size.

Output Blanking

If the input level is above the threshold level the pattern generator stops and only 0’s are sent on data output. Normal operation resumes when the input level is below the threshold.

Electrical Idle

If the input level is above the threshold level the output amplifier enters electrical idle. Normal operation resumes when the input level is below the threshold.

Gating Input

If a logical high is applied to the gating input the error detector will ignore the incoming bits during a BER measurement. The ignored bit sequence is always a multiple of the vector size. For measuring data in bursts of bits, rather than a continuous stream of bits, a special operating mode is used. This mode is the burst sync mode. In this case, the signal at the gating input controls the synchronization and the error counting for each burst.

NOTE

The M8070A system software (version 4.0 and above) supports certain real-time oscilloscopes to measure BER of NRZ signals and BER as well as SER of PAM4 signals. The real-time oscilloscope is completely controlled from M8070A to capture a signal and convert into a pattern stream that is then uploaded into the M8070A for comparison with an expected pattern and provide BER/SER measurements.

Nevertheless, it is possible to stop measuring BER on the integrated oscilloscope and therefore allow interactive tweaking of oscilloscope settings before continuing the BER measurements.

Currently, the following oscilloscopes are supported:

• DSOZ634A

• DSAZ634A

• DSOX96204Q

• DSAX96204Q

• DSAZ594A

Limitations

Know Your Hardware 2

The following are the limitations while using the M8046A and M8062A modules in the same setup:

• The M8046A does not support all sequencer word width settings of a M8041A/M8062A combination.

• Even though M8041A/M8062A and M8046A support a common sequencer word width of 1, they internally work with a different granularity and therefore cannot be used in the same sequence. Instead individual sequences need to be defined for M8062A Data Out, Data In and M8046A.

• In order to run the M8062A Data Out and M8046A Data In at the same symbol rate, the CLK IN frequency of M8046A needs to be specified manually. To do this, disable 'Follow SYS CLK' under Clock and specify CLK IN frequency and multiplier as required for the setup.

CAUTION

ESD Protection

Electrostatic discharge (ESD) can damage the circuits of the components on M8020A/M8030A/M8040A modules (M8041A, M8051A, M8061A, M8062A, M8045A, M8046A and M8057A). Avoid applying static discharges to the front-panel connectors. Before connecting any coaxial cable to the connectors, momentarily short the center and outer conductors of the cable together. Avoid touching the front-panel connectors without first touching the frame of the instrument. Be sure the instrument and all connected devices (DUT, etc.) are properly earth-grounded (to a common ground) to prevent buildup of static charge and electrical over-stress. Take necessary anti-static precautions, such as wearing a grounded wrist strap, to minimize the possibility of electrostatic damage.

Electrostatic discharge (ESD) can damage or destroy electronic components. All work on electronic assemblies should be performed at a static-safe work station. The following list and figure shows an example of a static-safe work station using two types of ESD protection. Purchase acceptable ESD accessories from your local supplier.

• Conductive table-mat and wrist-strap combination.

• Conductive floor-mat and heel-strap combination.

76 Keysight M8000 Series of BER Test Solutions User Guide

Know Your Hardware 2

WARNING

Both types, when used together, provide a significant level of ESD protection. Of the two, only the table-mat and wrist-strap combination provides adequate ESD protection when used alone. To ensure user safety, the static-safe accessories must provide at least 1 MW of isolation from ground.

These techniques for a static-safe work station should not be used when working on circuitry with a voltage potential greater than 500 volts.

Keysight M8000 Series of BER Test Solutions User Guide 77

2 Know Your Hardware

Discharging Cables

Loose cables are like a capacitor and can hold electrostatic charges. The free end of a cable touching surfaces that have voltage levels will cause product damage. Before connecting any cable to product connector, short the center and outer conductors of the cable together to ground momentarily.

You should use the cable discharger provided with the initial product shipment and shown in the following figures.

78 Keysight M8000 Series of BER Test Solutions User Guide

Know Your Hardware 2

While discharging a cable, make sure to ground the box appropriately, via the “GND” connector of the box, to the ground connector of the AXIe chassis as shown in the figure.

That is either directly using the accessories provided with the discharger like the grounding cable, or via an ESD mat, which is connected to the ground connector of the AXIe chassis.

Discharge your cables using the matching connector e.g. 2.40 mm (also for 1.85 mm), 3.50 mm (also for 2.92 mm) and Mini-Coax. You may stick the cable discharger box to your instrument/AXIe chassis e.g. using the fastener tape provided.

Fixture made of plastic can store charges, and probing powered devices can subject inputs to damaging voltage and power levels. Poor AC power supply connected to product or DUT may create AC transients, insufficient grounding, floating neutral lines which cause damaging currents to flow into or out of the instrument.

For more information about electrostatic discharge, contact the Electrostatic Discharge Association www.esda.org.
