Getting Started

This section begins with a brief description of the VX4380 256-Crosspoint Relay

Matrix Module, and explains how to configure and install the module in a

VXIbus mainframe. The quick functional check, also included in this section,

assures that the instrument operates properly.

Product Description

The VX4380 256-Crosspoint Relay Matrix Module is a printed circuit board

assembly for use in a mainframe conforming to the VXIbus Specification. The

VX4380 provides four 4 × 16 2-wire matrix sections. Each section can be

configured to connect either the four rows or the sixteen columns to the section

above or below it to produce up to a 16 × 16 2-wire matrix or a 4 × 64 2-wire

matrix. The VX4380 provides the following features:

Hhigh density single slot VXI relay matrix module with four 2-wire matrices

H2 A switching maximum current per contact

H220 VDC, 250 VAC maximum switching voltage per contact

H60 W, 125 VA maximum switching power per contact

Hlatching relays for low-power, low-noise operation

Htwo 160-pin DIN front panel connectors

Hlow-cost VXI local bus slave interface

HOption 01 – this option enables the VX4380 to control up to 11 additional

relay modules from the Tektronix family of relay modules. These modules

are controlled via the VXI P2 local bus.

H> 15 MHz bandwidth (– 3 dB) for 4 ×16 2-wire matrix

H> 15 MHz bandwidth (– 3 dB) for 16 ×16 2-wire matrix

User control of the VX4380 is achieved by installing the Option 01 VXI

Interface daughter board. This daughter board may be installed on the VX4380

or on another Tektronix compatible relay module which is installed in a VXI

chassis slot to the left of the VX4380. The Option 01 daughter board acts as a

VXI servant to a VXI bus commander. The VXI bus commander sends SCPI

compatible commands to the Option 01 daughter board using VXI word serial

protocol. The Option 01 daughter board in turn controls the VX4380 on which it

is installed and controls additional relay modules installed in adjacent slots to its

right via the VXI P2 local bus. The daughter board is capable of controlling from
