Sourcing and Measurement
The fundamental concepts of the U2722A/U2723A are as shown in Figure 2-1. 
When programmed to source voltage mode, the ammeter (I
meter
) is connected in 
series with the voltage source (V
source
) and the output. If the U2722A/U2723A is 
programmed to source current mode, the voltmeter (V
meter
) is connected across 
the current source (I
source
) and the output.
