PREPARATION FOR USE

INTRODUCTION

When the SVM2608 is unpacked from its shipping carton, the contents should include the following items:

(1)SVM2608 4 Channel 100 kSamples/s Analog-to-Digital Converter Module

(1)SVM2608 User’s Manual (this manual)

All components should be immediately inspected for damage upon receipt of the unit. Installation instructions for the module are discussed in the following pages of this section.

The chassis the SVM2608 is installed in should be checked to ensure that it is capable of providing adequate power and cooling. Once it is found that the chassis meets these specifications, the SVM2608 should be examined. If the module is found to be in good condition, the base address of the SVM2608 and the backplane jumpers of the chassis may be configured. After setting the base address and chassis jumpers, the SVM2608 may be installed into an appropriate 6U VMEbus mainframe in any slot other than slot zero.

CALCULATING SYSTEM POWER AND COOLING REQUIREMENTS

It is imperative that the chassis provide adequate power and cooling for this module. Referring to the chassis operation manual, confirm that the power budget for the system (the chassis and all modules installed therein) is not exceeded and that the cooling system can provide adequate cooling.

It should be noted that if the chassis cannot provide adequate power to the module, the instrument might not perform to specification or possibly not operate at all. In addition, if adequate cooling is not provided, the reliability of the instrument will be jeopardized and permanent damage may occur. Damage found to have occurred due to inadequate cooling could also void the warranty of the module.

SETTING THE CHASSIS BACKPLANE JUMPERS

Please refer to the chassis operation manual for further details on setting the backplane jumpers.
