Keysight Technologies N4951A-P32

32Gb/s Pattern Generator Remote Head

The Keysight (formerly Agilent) N4951A-P32 Pattern Generator Remote Head is available in 5 to 32 Gb/s configuration. This compact device offers compatibility with the N4960A Serial BERT controller and can be used to test up to 32 Gb/s per channel for 100 Gigabit Ethernet devices and other applications involving high-data rate devices. This N4951A-P32 Pattern Generator Remote Head also offers PRBS and user pattern support.

Key Specifications and Features of the Keysight (formerly Agilent) N4951A-P32:


  • 1 to 16 GHz with no remote heads connected
  • 2 to 8.5 GHz when one or two 17 Gb/s remote heads are connected
  • 2.5 to 16 GHz when one or two 32 Gb/s remote heads are connected

Frequency resolution:

  • 1 kHz (front panel)


  • Jitter (stressed), Delay, and Divided (non-stressed)

Output configuration (all outputs):

  • Differential, with amplitude, offset and termination voltage adjustment (can be used single-ended without terminating unused outputs)

Amplitude range:

  • 300 mV to 1.7 V (p-p), single-ended

Offset range:

  • ?2.4 to 2.4 V (limited by termination voltage, see Figure 24) on divided clock output, this is only valid when the divide ratio is a power of 2

Termination voltage range:
