The Keysight 81134A pulse pattern generator is a high-performance device with dual differential output channels designed for testing and developing high-speed digital devices. It provides a frequency range from 15 MHz to 3.35 GHz, making it ideal for applications requiring high precision and speed.

Key Features

• Dual differential output channels: Offer flexibility in testing multi-channel systems and multi-level signals.
• Fast rise time: Less than 60 ps (20%-80%), enabling accurate modeling of high-speed digital signals.
• Low intrinsic jitter: Ensures high accuracy and reliability in signal integrity testing.
• PRBS and custom pattern generation: Hardware-generated pseudorandom bit sequences (PRBS) and 12 Mbit memory per channel enable complex test sequences for various standards, such as Infiniband, PCI-Express, and Serial ATA.
• Adjustable crossover point and jitter emulation: Allow modeling of real-world operating conditions, including eye diagram distortion and jitter injection for system robustness evaluation.
• Output levels from 50 mV to 2 V: Support LVDS levels and pre-emphasis and signal de-emphasis for specific applications such as PCI Express and Serial ATA.
• Control interfaces: Remote control via GPIB, LAN (10/100 Mbps), and USB 2.0 ensures integration into automated test systems.

Applications

The Keysight 81134A is perfect for testing high-speed serial buses, such as PCI Express and Serial ATA, as well as evaluating the performance of receivers, backplanes, and other digital components where timing and signal integrity are critical.

Additional Features

• PC-based pattern control: Software for creating, modifying, and storing test sequences on a PC, with quick loading into the device via remote interfaces.
• Graphical user interface: Provides quick access to all relevant parameters, simplifying setup and generator operation.
