N4951B-H17/-H32 pattern generator high amplitude
remote head
The N4951B-H17/-H32 provides 6 V differential outputs suitable for directly driving
VCSELs, TOSAs and optical modulators without the need for external amplifiers. In addi-
tion to eliminating the need for extra signal connections and power supplies, integrating
the higher voltage driver inside the pattern generator allows direct amplitude control
from the same user interface with the other pattern generator controls.

The N4951B pattern generator also features improved rise/fall times and lower intrinsic
jitter performance to meet the needs of today’s characterization requirements in server,
line card, backplane and communications IC applications.
