The B2983B Femto/Picoammeter is the world’s only graphical picoammeter that allows you to confidently measure small currents with 0.01 fA (0.01 x 10-15 A) resolution. In addition, battery operation eliminates AC line noise from your critical measurements. It possesses a 4.3” color LCD with a graphical user interface that provides trend chart and histogram data in addition to numeric information. These front-panel capabilities enable you to capture transient behavior and to perform quick statistical analyses without a PC. The available Setup Integrity Checker software option allows you to compare the noise levels of different cabling and fixturing arrangements to help isolate external noise sources.
