Speciﬁcations-Pattern Generator

Figure 13. Generator connectors on front panel

Pattern generator key characteristics:

• Available as 7 and 12.5 Gb/s pattern generator without

error detector (Options G07 and G13), extension to

14.2Gb/s (Option D14)

• Differential outputs with variable output levels for data,

aux data, clock and trigger

• Low intrinsic jitter – 800 fs rms

• Transitions times < 20 ps

• Half-rate clock with variable duty cycle (Option 003)

• Pattern sequencer with up to 120 blocks and counted

loops

• Second output channel (Option 002)

• Calibrated and integrated jitter injection with SJ, two-

tone PJ, RJ/sRJ, BUJ, ISI, S.I. (Option J10, J20)

• SSC and residual SSC (Option J11)

• Automated jitter tolerance characterization sweep

makes use of SJ and PJ using 610 ps or 220 ps delay

line

• High precision delay control input to inject jitter from

an external source

• Electrical idle state on data outputs
