The Keysight 1147A is a wide bandwidth, active current probe for 54800, 3000X, 5000, 6000, 7000, 8000, and 9000 Series oscilloscopes except the 6000 100 MHz models. 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.
The Keysight 1147A is now discontinued. The 1147B current probe is the recommended replacement product.
Key Features:
- Wide bandwidth: DC to 50MHz
- High S/N ratio, low current measurement capability
- 15A peak, 15 ADC, 10 Arms continuous, 30A peak non-continuous
- Easy protect function at excessive input
- Demagnetizing switch to remove any residual magnetism that builds up in the magnetic core
- Compatible with high impedance AutoProbe interface
- For use with 80000/90000 Series, use N278xA current probe with N2779A power supply and E2697A high impedance adapter
- For use with 90000 X-Series, use the N5449A high impedance probe adapter
