Description
Serial links now run so fast that a small amount of jitter can decide whether a receiver passes. The Keysight M8050A BERT targets that edge, with symbol rates from 2 to 120 GBd. A BERT is a bit error ratio tester, so it sends patterns and counts the errors. Lost in HCM lists the M8050A for rental and sale, and it arranges service on request.
Headline specifications
| Symbol rate | 2 to 120 GBd |
|---|---|
| Channels | 1 or 2, depending on configuration |
| Line coding | NRZ, PAM3, PAM4, PAM6 and PAM8 |
| De-emphasis | Built-in, seven taps |
| Transition time | Under 5 ps |
| Intrinsic random jitter | Under 100 fs rms |
Installed modules, options and licenses change what a given unit can do. So the serial-number configuration and the formal quote take priority over this table.
Why the Keysight M8050A BERT suits 224G work
Receivers on 800G and 1.6T Ethernet links face signals with tight margins. Therefore the tester must add its own impairments in a controlled way. The M8050A includes jitter injection and de-emphasis for exactly that, so you can check receiver tolerance instead of only the clean case. Teams working toward OIF CEI-112G and 224G lanes also look at this class of instrument.
Many formats, one platform
One platform spans several standards. PAM4 serves many data-center links, while PAM6 and PAM8 appear in research on faster lanes. You can also run NRZ for older interfaces. Besides Ethernet, the formats support PCIe Gen 6 and 7 and USB4 validation. Because the system is modular, you pick the pattern generator, error analyzer and remote-head parts that your test needs.
Typical users
- Transceiver and SerDes teams characterizing data-center components
- Labs validating PCIe and USB4 silicon before release
- Research groups exploring higher-order modulation on fast lanes
Planning your Keysight M8050A BERT order
A short project can justify a rental, because this class of equipment costs a lot to own. In contrast, a lab that runs receiver tests every month may prefer to buy. Either way, list the rate, line coding, channel count, modules, remote heads and software you need. Not every unit reaches 120 GBd, since the result depends on the installed generator, error analyzer and licenses.

M8050A questions
Does every M8050A reach 120 GBd?
No. The rate depends on the installed pattern generator, remote head, error analyzer and software licenses.
Can I buy a configured system?
Yes, subject to current module, chassis and license availability. Lost in HCM confirms this in the quote.
Which coding schemes does it support?
The listing names NRZ, PAM3, PAM4, PAM6 and PAM8.
