Page 18

2.1Required Equipment

-One double-output dc power supply (±5 V, 100 mA output minimum)

-Two dc current meters with resolution to 1 mA and capable of the maximum current the dc power supply can 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-Ωsource impedance function generator (1 MHz, 10 VPP sine wave)

-Oscilloscope (50-MHz bandwidth minimum, 50-Ωinput impedance).

2.2Power Supply Setup

1)Set the dc power supply to ±5 V.

2)Make sure the dc power supply is turned off before 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)Connect the negative (±) terminal of the current meter number 1 to the VCC+ of the EVM (J7).

5)Connect the common ground terminal of the power supply to the ground GND on the EVM (J9).

6)Connect the negative (±) terminal of the power supply to the negative (±) terminal of the second current meter.

7)Connect the positive (+) terminal of the current meter number 2 to the VCC± of the EVM (J8).
