Section 3: Performance Verification
Model 2231A-30-3 Triple-Channel DC Power Supply Performance Verification
3-24
077102700/ July 2014
Channel
Reference test voltage
Channel 1
15.0V
Channel 2
15.0V
Channel 3
2.5V
8. Enter the voltmeter reading into the table for DC current load regulation at the reference test
voltage for the channel under test.
9. Increase the electronic load to the maximum test voltage level.
Channel
Reference test voltage
Channel 1
29.4V
Channel 2
29.4V
Channel 3
4.9V
10. Enter the voltmeter reading into the table for DC current load regulation at the maximum voltage
for the channel under test.
11. Calculate the two values: REF – Min and Max – REF. Enter the values into the appropriate
columns.
12. Select the larger of the two calculated values from step 11 and enter the value into the Largest
column.
13. Power off the DUT and test equipment.
This completes the verification procedure for one channel. If needed, return to step 1 to run through
the procedure for the next channel.
Check Voltage Noise (7 MHz)
Equipment required
High current hookup wire
(bold line connections)
Oscilloscope
Load resistor
Oscilloscope 1X probe
For each channel sequentially.
1. Plug the DUT into your local line power from the mains.
2. Plug the test oscilloscope into the same mains outlet as the DUT.
