Power Up and Power Down Procedure

5.1

Power Up

1. Before proceeding with the power up test procedure, ensure that the steps in

are

complete. Then,

can be used as a reference for the expected behavior of the EVM.

2. Enable power supply 1. The quiescent current on DMM1 should be approximately 1mA to 2mA.

3. Enable power supply 2. The quiescent current on DMM2 should be approximately 0.75 mA to 2 mA if

everything is set correctly.

4. Enable the function generator outputs.

5. Verify that the following occurs:

1. Stable pulse output appears on channel 1 in the oscilloscope, see

2. Oscilloscope frequency measurement matches programmed function generator frequency.

3. DMM2 current should read 6.5 ± 0.5 mA with the default 1.8-nF load installed. For more

information about the operating current, see the applications section of the

UCC5304 data sheet
