Series 2200 Programmable DC Power Supplies Reference Manual

Appendix B: Calibration

2200S-901-01 Rev. C / March 2016

B-37

5. Set the oscilloscope as follows:

a. 1 mV/division

b. 1 M

Ω

input resistance

c. 20 MHz bandwidth (BW) limit

d. AC Coupled

e. Auto-trigger

f. 1 ms/div

g. Set to measure Vp-p and VRMS

6. Set the DUT to the 100% FS output voltage.

7. Set the DUT to the 100% FS output current.

8. Turn the DUT output on.

Do not touch the load resistor. The load resistor may become hot enough to cause burns.

9. Enter the oscilloscope measurements into the

Current noise at 20 MHz

(on page B-10) table for

checking current noise.

10. Power off the DUT and test equipment.

This completes the performance verification procedure.
