Agilent Technologies 60502B, 60501B CC Mode PARD Test, CC Mode Power Limit, 3. Test Setup C

h.Adjust the oscilloscope for a single rise or fall time display. Use delayed sweep. The rise time when measured from

10% to 90% or the fall time when measured from 90% to 10% should be between: 60501B: 0.6 and 1.0ms.

60502B: 1.5 and 2.5ms.

CC Mode PARD Test

CCmode PARD (periodic and random deviations) is specified as the rms input current in a frequency range 20Hz to 10Mhz. This test checks CC Mode PARD.

a.Connect the Electronic Load, power supply (Agilent 6032A or equivalent, DMM, and current probe as shown in Figure 2-3. Set power supply for 10V and >10A.

b.Turn the load's ac power off then on.

c.Press .

d.DMM reading should be less than:

60501B: 2mA rms.

60502B: 4mA rms.

CC Mode Power Limit

This test verifies that the module's power limit circuit is operating properly. If the results specified in steps d through i are not obtained, troubleshoot the circuits as described in "Overpower Circuits Troubleshooting" in Chapter 3 of the mainframe Service Manual.

If the overpower circuit does not turn the load off within three minutes after performing step d, stop the tests and troubleshoot the overpower circuits.

a.Connect the Electronic Load and the power source as shown in Figure 2-2.

b.Turn on the Electronic Load and run for approximately five minutes with no power being dissipated (no input power).

c.Then press, then.

d.Turn on and set the power supply for: 60501B: 34volts and 10mps.

60502B: 34volts and 18mps.
