2.4 Operating the EVM on Channel 1
1) Turn on the dc power supply.
2) Verify that both the +15 V (current meter 1) and the –15 V (current meter
2) currents are below 25 mA.
Currents above the limits stated above indicate a possible short or
a wrong resistor value on the PCB. Do not proceed until this
situation is correct.
3) Turn on the function generator.
4) Verify the oscilloscope is showing two 1-MHz sine waves, the input with
an amplitude of ±0.484 V and the output with an amplitude of ±0.242 V as
shown in Figure 2--3. They should be 180° out out of phase. See Section
3.1 for an explanation of these voltage values.
