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.
If a balanced (differential) signal is inserted into J2 and J4, a balanced signal
is present at J1 and J3.
