N1060A Precision Waveform Analyzer.

The Keysight Technologies N1060A Precision Waveform Analyzer is a plug-in module used with oscilloscopes to deliver an ideal solution to measurement challenges faced by design and validation engineers.
Accurately characterize the true performance of high-speed electrical communication systems and components.Bandwidth > 90 GHz allows you to gain margin with high instrument performance
Residual jitter as low as 50 fs
Adjustable clock recovery peaking & loop BW
Decrease development time through instrument flexibility:
integrated clock recovery data rates to 64 GBd (112 Gb/s) (NRZ & PAM4) and integrated pickoffs for simple one connection ‘triggerless’ operation
Cut down validation time with analysis tools like Jitter Spectrum Analysis & SW Clock Recovery Emulation
