The Agilent 1153A is a 1:1 FET differential probe with 3000:1 CMRR (Common Mode Rejection Ratio) at 1 MHz & 200 MHz bandwidth. The probe’s got a 1 MΩ input resistance and 7 pF low input capacitance in order to lessen circuit loading. Compatible with the 90000, 9000, 80000, 87000, and 54800 Series oscilloscopes. This probe isn’t compatible with Agilent’s 7000, 6000, or 5000 Series oscilloscope. With the BNC probe interface, order the 1141A differential active probe and the 1142A power supply for use with 7000/6000/5000 Series
