2-2
Figure 2−1 shows the connections to measure the output signal of output 1
while a single-ended signal is inserted into EVM channel 1’s noninverting
input. If the oscilloscope input is connected to J3 and the signal source is
connected to J2, EVM channel 2 is also configured for a noninverting signal
path. When the oscilloscope’s input impedance is 50 Ω, the voltage gain from
J2 to J3 is 1.33 V.
Once power is available at the power terminals of the EVM, removing either
JP1 and/or JP2 causes bias current to flow at the desired amount. With both
JP1 and JP2 installed, the circuit is disabled.
If a balanced (differential) signal is inserted into J2 and J4, a balanced signal
is present at J1 and J3.
