Description This command is used to select the units for ACV measurements. With volt
(V) units selected, normal AC voltage measurements are made for the ACV
function. With DB units selected, AC dB voltage measurements are per-
formed. The DBM units selection is used to make decibel measurements ref-
erenced to 1mW. dB and dBm measurements are explained further in
Section 2.
