Keysight / Agilent / HP E8305A 250 MHz Pulse Pattern Generator

The Keysight/Agilent/HP E8305A is a 250 MHz Pulse Pattern Generator housed in a VXI C-size, single-slot module for integration into VXI mainframe systems. This dual-channel instrument delivers precise pulse parameter control across a 1 mHz to 250 MHz frequency range, making it suitable for high-speed digital circuit characterization, signal integrity analysis, and component testing across TTL, CMOS, ECL, PECL, LVDS, and GTL logic technologies.

## Technical Specifications

• **Maximum Frequency:** 250 MHz
• **Frequency Range:** 1 mHz to 250 MHz
• **Channels:** 2
• **Data Pattern Memory:** 16 kbit per channel, user-defined
• **Pattern Formats:** Pseudo-Random Binary Sequence (PBRS, n = 7 to 14); Return-to-Zero (RZ) and Non-Return-to-Zero (NRZ)
• **Pulse Parameters:** Glitch and dropout-free variation of pulse width and delay with timing calibration for enhanced DUT characterization accuracy

## Key Features

• VXI form factor supports direct integration into existing mainframe systems
• Identical programming syntax and pattern capabilities to the 81110A and other VXI Pulse Pattern Generators
• SCPI command structure via VXIplug&play drivers with Passthrough Functions
• Logic technology support spans legacy (TTL, CMOS, ECL) and modern (PECL, LVDS, GTL) standards
• Timing calibration feature enhances measurement precision during device characterization

## Typical Applications

• High-speed digital circuit testing and validation
• Signal integrity analysis
• Component and subassembly characterization
• Production test environments requiring modular, scalable solutions

## Compatibility & Integration

The E8305A operates within VXI mainframe systems and requires VXIplug&play driver installation on the control PC. Documentation and drivers are supplied via Part No. E8305-10011. The instrument operates indoors at Installation Category II, Pollution Degree 2, with maximum relative humidity of 95% and altitude operation up to 2000 meters. Safety Class 1 designation with protective earth terminal; all LEDs are Class 1 per IEC 60825-1.
