Agilent Technologies 60501B, 60502B service manual Transient Operation and Slew Circuit Test

Transient Operation and Slew Circuit Test

This test verifies transient and slew circuit operation. The slew circuits cannot be calibrated. If slew rise time and/or fall time are not within specifications or the slew circuits are inoperative, perform either the "Transient Generator Troubleshooting", or the "Slew Circuit Troubleshooting" in Chapter 3 of the mainframe Service Manual.

a.Use the test setup of Figure 2-1 except connect an oscilloscope across the 0.10 current monitor resistor in place of the DMM. Set power supply for:

60501B: 5V and 5A.

60502B: 10V and 10A.

b.Recall the factory default values by pressing .

c.Select the low current range by pressing

60501B: .

60502B: .

d. Set up transient operation by pressing , then

60501B:.

60502B:.

e.Set the slew rate to .05A/∝s (50A/ms) by pressing

(blue shift key), then

, then .

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

10% to 90% or the fall time when measured from 90% to 10% should be between: 60501B: 30 and 50∝s.

60502B: 75 and 125∝s.

Note that the Electronic Load's Tran annunciator is on.

60501B: 10∝s/DIV

60502B: 20∝s/DIV

SLEW 0.05

g.Set the slew rate to .0025A/∝s (2.5A/ms) by pressing (blue shift key), then , then .
