The HP/Agilent 8170A is an 8-channel data generator delivering 2 Mbit/s pattern stimulus for digital communication systems and logic device testing. With 4 Kbit memory per channel and clocking from 20 Hz to 2 MHz, it provides synchronized multi-channel signal generation across TTL and POD output formats. Front-panel and remote programming via RS-232C or HP-IB enable flexible test automation and real-time pattern control.
Technical Specifications
• Data Rate: 2 Mbit/s
• Channels: 8
• Memory Depth: 4 Kbit per channel
• Data Bus Format: 8-bit or 16-bit
• Clocking Frequency: 20 Hz to 2 MHz (five decade ranges)
• Handshake Protocol: 2-wire and 3-wire support
• Output Lines: 16 POD lines plus five standard TTL lines
• Physical: 12 in × 10 in × 8 in; approximately 10 lbs
– Key Features
• Independent per-channel pattern memory enables complex stimulus scenarios across eight parallel data paths
• Wide frequency range accommodates both low-speed handshake protocols and mid-speed digital interfaces
• Dual programming interfaces (RS-232C/CCITT V.24 and HP-IB/IEEE 488) permit both local and remote test control
• Mixed output standards—POD and TTL—support legacy and contemporary logic levels
• Flexible bus widths adapt to 8-bit or 16-bit test requirements
– Typical Applications
• Multi-channel logic device and subassembly characterization
• Digital communication link stimulus and verification
• Multiplexer and data terminal testing
• Communication network protocol validation
• Real-time pattern generation for receiver and decoder qualification
– Compatibility & Integration
The 8170A integrates with standard digital test systems via IEEE 488 and serial interfaces. Its 16 POD output lines and TTL drivers interface directly to logic devices, multiplexers, and communication equipment requiring synchronized multi-channel stimulus.
