2.4Testing the EVM Setup

1)Turn on the dc power supply.

2)Verify that both the +5 V (current meter 1) and the ±5 V (current meter 2) currents are below 20 mA.

Caution:

Currents above 20 mA indicate a possible short or a wrong resistor value on the PCB. Do not proceed until this situation is corrected.

3)Turn on the function generator.

4)Verify the oscilloscope is showing two 1 MHz sine waves with amplitude of ±0.125 V. The dc offset of the signal must be below 50 mV.

Note: VOUT+ and VOUT± should be 180 degrees out of phase. The internal attenuation of the scope should be set to 6 dB for a gain of one. Otherwise,

the output will show a gain of one-halfdue to the voltage division occurring at the 50-Ωtermination resistor.

Use Figure 3 as a reference for the input and output signals.
