Verification and Calibration
Introduction
This appendix includes verification and calibration procedures for the Agilent E4350B and E4351B SAS. Instructions are
given for performing the procedures either from the front panel or from a controller over the GPIB.
The verification procedures do not check all the operating parameters, but verify that the Agilent SAS is performing
properly. Performance Tests, which check all the specifications of the dc source, are given in the applicable Service Manual.
The required test equipment and acceptable test results are specified in tables in this appendix.
Note Performance Tests, which check all the specifications of the Agilent SAS, are given in the Service
Manual.
Test Equipment Required
The following equipment is required to perform the tests:
Table B-1. Equipment Required for Verification and Calibration
Equipment Characteristics Recommended Model
Digital Voltmeter
Resolution: 10 nV @ 1 V
Readout: 8 1/2 digits
DC Accuracy: 0.005%, 6 digits, 20 ppm
Agilent 3458A
Current Monitor Resistor
15 A, 0.1
, 0.04%, 25 W
Guildline 9230/15
For Calibration Over the GPIB
HP Vectra (or IBM compatible) with GPIB Interface, or Agilent BASIC
series
Current Monitoring Resistor
The 4-terminal current-monitoring resistor listed in Table B-1 is required to eliminate output current measurement error
caused by voltage drops in leads and connections. The specified resistors have special current-monitoring terminals inside
the load connection terminals. Connect the DVM directly to these current-monitoring terminals.
