5 Power Up and Power Down Procedure
5.1 Power Up (C
L
= 1000 pF)
1. Before proceeding to the power up procedure, make sure that Section 4.3.6 is implemented for setting
up all the equipment. Figure 3 can be used as reference.
2. Enable supply #1.
3. Enable supply #2.The quiescent current on DMM1 and DMM2 ranges in 1 mA to 3 mA if everything is
set correctly.
4. Enable function generator output.
5. Afterward, the following occurs:
1. Stable pulse output on the channel-A and channel-B in the oscilloscope. See Figure 3 .
2. Scope frequency measurement is the same as function generator output.
3. DMM #1 and #2 should read measurement results around 5 mA–10 mA under no load conditions.
For more information about operating current, refer to the corresponding datasheet.
