HP E1466A VXI 4x64 Relay Matrix

Product Summary

The HP E1466A relay matrix is a C-size, 1-slot, register- based VXI module. This 4x64 matrix switches each crosspoint- both high and low. The HP E1466A module provides the best cost-per-crosspoint for large matrix applications. It features easy expansion to larger matrixes via a chaining cable that allows you to interconnect rows and columns on different modules. A full HP E1401B 13-slot mainframe can have up to 3072 2-wire crosspoints.

The HP E1466A shares the same switch card with the HP E1465A and E1467A; each product’s unique terminal block determines the matrix configuration. Therefore, you can change matrix topology simply by plugging in the various terminal blocks, which can be obtained separately. Creating a matrix as large as 4x256 requires three matrix modules and interconnected rows and columns on the terminal blocks. All of the HP E1465/66/67A matrix modules offer similar densities, with different row/column sizes and identical performance specifications. All specifications are identical for this family, except for crosstalk.

Product Features

• 4x64 2-wire switching matrix
• Rows expand to make larger matrixes with an optional daisy-chain cable
• Downloadable channel lists into onboard memory for higher system throughput
• Interchangeable terminal blocks allow changing between three matrix types
• Includes HP QUIC easy-to-use terminal blocks
• Latching armature relay
• VXIplug&play frameworks are supported per the Instrument Drivers information listed below.

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.

Crosstalk(1)
Within a Card (worst path)			<10 kHz		<100 kHz	<1 MHz
	Closed Path to Closed Path (typical)(3)	-66 dB		-45 dB		-29 dB
	Open Row to Open Row (typical)(3)	-73 dB		-52 dB		-37 dB

NOTES:	(1) Specifications are for worst crosspoint. Matrix expansion degrades crosstalk and
	    bandwidth performance.
	(2) Chaining cable used to connect modules (HP P/N E1466-80002).
	(3) Typical is defined as the worst crosspoint test result from one or two matrix 
	    modules. If guaranteed specifications are necessary, contact your local sales 
	    representative.
