Performance Verification Verification Description .............. 12 Verification Procedure ..............14 Constant Current Tests .............. 17 Test Record Forms..............20 The verification procedures described in this chapter verify that the Keysight E4360 Series Solar Array Simulator is operating normally and is within published specifications. -
Page 12: Verification Description
If the solar array simulator fails any of the tests or if abnormal test results are obtained, try calibrating the unit. If calibration is unsuccessful, return the unit to a Keysight Technologies Service Center. Equipment Required The equipment listed in the following table, or the equivalent to this equipment, is required for the performance tests and for calibration. - Page 13 Performance Verification Measurement Techniques Voltmeter To ensure that the values read by the voltmeter during both the verification procedure and the calibration procedure are not affected by the instantaneous measurement of the AC peaks of the output current ripple, several DC measurements should be made and averaged. If you are using a Keysight 3458A DMM, you can set up the voltmeter to do this automatically.

Page 14: Verification Procedure
Performance Verification Verification Procedure Constant Voltage Tests Test each output channel individually. Refer to the appropriate test NOTE record form for the instrument settings of the model you are checking. Voltage Programming and Readback Accuracy Test category = performance, calibration This test verifies that the voltage programming and measurement functions are within specifications. - Page 15 Performance Verification CV Load Effect Test category = performance This test measures the change in output voltage resulting from a change in output current from full load to no load. Turn off the solar array simulator and connect a DMM and an electronic load (see Test Setup figure A).
- Page 16 Performance Verification CV Ripple and Noise Test category = performance Periodic and random deviations in the output combine to produce a residual AC voltage superimposed on the DC output voltage. This residual voltage is specified as the peak-to-peak or rms noise in the frequency range specified in Appendix A in the User’s Guide.
-
Page 17: Constant Current Tests
Performance Verification Disconnect the oscilloscope and connect an rms voltmeter in its place. Do not disconnect the 50 ohm termination. Program the solar array simulator to Fixed mode. Set the instrument as indicated in the in the test record form under “CV Ripple and Noise” and enable the output. - Page 18 Performance Verification Divide the voltage drop (DMM reading) across the current shunt by the shunt resistance to convert to amperes and record this value (Iout). Also, record the current reading measured over the interface. The readings should be within the limits specified in the test record form under “Current Programming and Readback, High Current”.
- Page 19 Performance Verification CC Source Effect Test category = performance This test measures the change in output current that results from a change in AC line voltage from the minimum to maximum value within the line voltage specifications. Turn off the solar array simulator and connect the ac power line through a variable voltage transformer or AC source.
