Performance Test and Calibration Procedures

Introduction

This appendix contains test procedures for checking the operation and calibration of the Agilent N330xA Series Electronic Load Modules. The tests are performed using the front panel keypad of the N3300A or N3301A Mainframes. The required test equipment is listed in Table B-1 and sample performance test record cards are included at the end of the performance test section. The performance tests confirm the Agilent N330xA Series Electronic Load Modules meet all their published specifications.

The calibration ( adjustment ) procedures create new calibration constants to bring the current, voltage and resistance values within specifications. Calibration cannot be performed using the front panel keypad, an IEEE- 488 ( GPIB ) controller is required. Note that the Electronic Load Mainframe does not require calibration.

Important Perform the verification procedures before calibrating your Electronic Load Module. If the Electronic Load Module passes the verification procedures, the unit is operating within its calibration limits and does not need to be re-calibrated.

If the electronic load requires service, refer to the list of Agilent Sales and Support Offices at the back of this manual.

Equipment Required

The equipment listed in the following table, or the equivalent to this equipment, is required for verification and calibration. An IEEE-488.2 controller is not required for verification.
