Operation and Features 2Keysight U2722A/U2723A User’s Guide 45Remote sense and guardRemote senseThe U2722A/U2723A has both local and remote sensing capabilities. Whenremote sensing is applied, the sense lines can be directly connected to the DUT.When the U2722A/U2723A is in source voltage mode, remote sensing enablesthe voltage to be sensed at the load and it will result in better regulation. If theremotely sensed voltage at the DUT is lower than the programmed voltage level,the actual output voltage will be increased until the sensed voltage matches theprogrammed voltage. This ensures that the exact programmed voltage appears atthe DUT.Remote sensing is especially useful in source voltage mode with load impedancesthat vary or have significant lead resistance. It has no effect in source currentmode.Figure 2-9 Local sense connectionSENSE+OUTPUT+GUARDOUTPUT–SENSE –+–DUT
