Verification
Introduction
This chapter provides test procedures for checking the operation of Agilent Series 668xA power supplies. The required test
equipment is specified and sample performance test record sheets are included. Instructions are given for performing the
tests either from the front panel or from a controller over the GPIB.
Tests
Two types of procedures are provided: Operation Verification tests and Performance tests.
Type of Test
Purpose
Operation Verification
These tests do not check all parameters, but comprise a short procedure to verify that the power
supply is performing properly.
Performance
These tests verify all the Specifications (not Supplementary Characteristics) listed in Table 1-1
of the Power Supply Operating Manual.
If you encounter failures or out-of-specification test results, see Troubleshooting Procedures (Chapter 3). The procedures
will determine if repair and/or calibration is required.
Note The power supply must pass the selftest at power-on before the following tests can be performed. If the
power supply fails selftest, go to Chapter 3.
Test Equipment Required
List of Equipment
Table 2-1 lists the equipment required to perform the tests given in this chapter. Only the equipment marked with the
superscript "
1
'' is needed for the Operation Verification test.
Current-Monitoring Resistor
The four-terminal, current-monitoring resistor (current shunt) listed in Table 2-1 is required to eliminate output current
measurement error caused by voltage drops in leads and connections. The specified current shunts have special
current-monitoring terminals inside the load connection terminals. The accuracy of the current shunt must be 0.04% or
better. When using the 1000 amp 0.05% current shunt the measurement uncertainty should be stated for all calibrations.
Connect the current monitor directly to these current-monitoring terminals.
