03 | Keysight | N4960A Serial BERT 17 and 32 Gb/s - Data Sheet
Integrated 32 Gb/s operation
Pattern generator and error detector remote heads are available in two data rate verions:
– 17 Gb/s versions operate over 4 to 17 Gb/s
– 32 Gb/s versions operate over 5 to 32 Gb/s
Both versions operate over their entire band with no gaps or missing data rates. The
numbers 17 or 32 form the last two digits of the model/option number and indicate the
data rate range of the remote head. For example,
– N4951A-P32 pattern generator operates over 5 to 32 Gb/s;
– N4952A-E17 error detector operates over 4 to 17 Gb/s
Figure 2. Typical eye at 14 Gb/s.
The remote heads generate and test full rate patterns directly without the need for
external multiplexers and delay matching. Each includes a selection of PRBS pattern
lengths, along with a large selection of common telecom, datacom, and clock stress test
patterns including K28.5, CJPAT, CJTPAT, JSPAT, JTSPAT, etc.
Pattern generator heads are available in N4951A and N4951B models.
The signal fidelity in the eye is outstanding. Output parameters of amplitude, offset, and
termination voltage are user settable.
Each N4960A controller can support
0 remote heads
1x pattern generator head only
1x error detector head only
1x pattern generator and 1x error detector head
2x pattern generator heads
Complete, compact, flexible configurations 17 Gb/s
and 32 Gb/s BERT
Does your application need a full BERT? Keysight offers a surprisingly affordable total
solution which includes both pattern generation and error detection capability. Tied
together with our N4980A multi-instrument BERT software, this combination provides a
powerful BERT solution.
Of course, the system also operates without the error detector or pattern
generator, for applications which require these configurations.
Alternatively two pattern generators can be connected to a controller with programma-
ble delay skew control between the generators for use in I-Q modulator applications.
