Showing Results for Tektronix AM503

The AM503 current-probe amplifier allows display of current on any oscilloscope having 10 mV/div sensitivity, 50 Ω or 1 MΩ input, and (for performance to full bandwidth) at least 100 MHz bandwidth. The amplifier attenuator has 12 calibrated steps in a 1-2-5 sequence, and the knob-skirt is illuminated to indicate current / division. The AM503 forms current probe systems with the A6302 and A6303.

The AM503S package includes the AM503 with the A6302 or the A6303 or both.

• Maximum input current (dc + peak ac): 20 A with A6302, 100 A with A6303
• Maximum voltage for current under test - bare conductor (dc + peak ac): 500 V with A6302, 700 V with A6303
• -3 dB bandwidth: dc to at least 50 MHz with A6302, dc to at least 15 MHz with A6303
• Full bandwidth rise time: 7 ns or less with A6302, 23 ns or less with A6303
• Deflection factor: 1 mA/div to 5 A/div for A6302, 20 mA/div to 50 A/div for A6303
