Additional Features: Frequency range: DC to 100 kHz (-3dB with current derating) Current range: 100 mV/A: 100 mA to 10 A peak, 10 mV/A: 1 to 100 A peak AC current accuracy, 100 mV/A (50 mV to 10 A peak) - 3% of reading ≥50 mA 10 mV/A (500 mA to 40 A peak) - 4% of reading ≥50 mA 10 mV/A (40 A to 100 A peak) - 15% max at 100 A Working voltage: 600 V max Battery: 9 V alkaline The Agilent 1146A AC/DC current probe provides accurate display and measurement of currents from 100 mA to 100 A rms, dc to 100 kHz, without breaking the circuit. The 1146A uses Hall-effect technology to measure ac and dc signals. It is compatible with all Agilent oscilloscopes and any scope with 0.2 to 0.5 V/div sensitivity, a minimum input impedance of 1 MΩ and a BNC input. Compatible with the 1000, 3000, 5000, 6000, 7000, 8000, 9000, 80000 (with E2697A) and 90000 (with E2697A) Series oscilloscopes.
