Appendix B Verification and Calibration

4Program the power supply to program the output current to its maximum programmable value (Imax) and the output voltage to its full-scale value and enable the output. Let the oscilloscope run for a few seconds to generate enough measurement points. On the Agilent Infiniium scope, the maximum peak-to-peak voltage measurement is indicated at the bottom of the screen on the right side. Divide this value by 10 to get the CV peak-to-peak noise measurement. The result should not exceed the peak-to-peak limits in the test record form for the appropriate model under CV Ripple and Noise, peak-to-peak.

(If the measurement contains any question marks, clear the measurement and try again. This means that some of the data received by the scope was questionable.)

5Disconnect the oscilloscope and connect an ac rms voltmeter in its place. Do not disconnect the 50 Ω termination. Divide the reading of the rms voltmeter by 10. The result should not exceed the rms limits in the test record card for the appropriate model under CV Ripple and Noise - rms.

Transient Recovery Time

Test category = performance

This measures the time for the output voltage to recover to within the specified value following a 10% to 90% change in the load current.

1Turn off the power supply and connect the output as in figure A with the oscilloscope across the +S and -S terminals.

2Turn on the power supply and program the output current to its maximum programmable value (Imax) and the output voltage to its full-scale value. Do not program voltages greater than 200 VDC when testing the 300 and 600 volt models.

3Set the electronic load to operate in constant current mode. Program its load current to 10% of the power supply’s full-scale current value.

4Set the electronic load's transient generator frequency to 100 Hz and its duty cycle to 50%.

5Program the load's transient current level to 90% of the power supply's full-scale current value. Turn the transient generator on.

6Adjust the oscilloscope for a waveform similar to that shown in the following figure.

7The output voltage should return to within the specified voltage in the specified time following the 10% to 90% load change. Check both loading and unloading transients by triggering on the positive and negative slope. Record the voltage at time “t” in the performance test record card under Transient Response.
