Agilent/Keysight 1153A 200 MHz 1:1 FET Differential Probe


The Agilent 1153A is a 1:1 FET differential probe with 200 MHz bandwidth and 3000:1 CMRR (Common Mode Rejection Ratio) at 1 MHz. The probe has an input resistance of 1 MΩ and low input capacitance of 7 pF to minimize circuit loading. Compatible with the 54800, 87000, 80000, 9000, and 90000 Series oscilloscopes.

This probe is not compatible with Agilent’s 5000, 6000 or 7000 Series oscilloscope. Order the 1141A differential active probe with BNC probe interface and the 1142A power supply for use with 5000/6000/7000 Series.
