HP E1458A VXI 96-Channel Digital Input/Output

Product Summary

The HP E1458A 96-Channel Digital Input/Output module is a C-size, 1-slot, register-based VXI module that offers twelve 8-bit bi-directional data ports. It provides block memory transfers and six GPIO handshake protocols (none, leading edge, trailing edge, pulse, partial, and strobe) for a wide range of applications.

Functionally similar to the HP E1330B, the HP E1458A is intended for digital I/O control applications such as digital subassembly test or data acquisition and control. Each of the 12 identical ports consists of eight data lines and six handshake/control lines.

Each 8-bit port is individually configured for positive/negative true logic and read/write or tri-state condition. The HP E1458A is arranged into three banks of four ports each. Ports can be combined within a bank, allowing data transmission using bytes, words (16-bit), or long words (32-bit). Data transmission can be from a single port (8 bits) or from multiple ports up to all 12 ports.

Product Features

• Twelve 8-bit input or output data ports for acquisition
• Wide variety of output data types
• Data port readback on a per-port basis
• Control of interface driver tri-state capability
• Block mode transfer to/from memory

Note: Configuration software that allows you to easily select compatible interfaces, controller platforms, and VXI test system components is available on CD ROM. Order the "Test System and VXI Products Catalog and CD ROM" from the Test & Measurement Catalogs available on this web site.
