2.1 Required Equipment

- One double-output dc power supply (±15 V, 1-A output minimum)

- One single-output dc power supply (+5V, 100-mA output minimum) –

referred to in this document as a shutdown supply

- Two dc current meters with resolution to 1 mA and capable of the

maximum current from the dc power supply. If available, set the current

limit on the dc power supply to 100 mA.

NOTE: Some power supplies incorporate current meters which may be

applicable to this test.

- 50-W source impedance function generator (1-MHz, 10-V

sine wave)

- Oscilloscope (50-MHz bandwidth minimum, 50-W input impedance).

2.2 Power Supply Setup for ±15 Vdc

1) Set the dc power supply to ±15 V.

2) Make sure the dc powersupply is turned offbefore proceeding to the next

step.

3) Connect the positive (+) terminal of the power supply to the positive (+)

terminal of the current meter number 1.

4) Connectthenegative(–)terminalofthecurrentmeternumber1tothe+VS

terminal of the EVM (J1).

5) Connect the common ground terminal of the power supply to the ground

(GND) terminal on the EVM (J2).

6) Connect the negative (–) terminal of the power supply to the negative (–)

terminal of the second current meter.

7) Connect thepositive (+)terminalof thecurrent meternumber 2to the --VS

of the EVM (J3).

8) Connect the negative terminal (--) ofthe shutdown supply to the GND ter-

minal of the EVM (J2).

9) Connect one end of atest lead to thepositive terminal (+)of theshutdown

supply. Connecttheother endto theshutdown terminal ofthe EVM(J10).
