To The Agilent 1147A is a wide bandwidth, active current probe for 54800, 5000, 6000, and 8000 Series oscilloscopes except the 6000 1 MHz model. The probe features flat bandwidth (DC-50MHz), low noise(<2.5 mA rms) and low circuit insertion loss. The 1147A is ideal for capturing transient current signals such as those found in motor controllers, in switching power supplies, inverters and current amplifiers driving inductive loads.
