N2870A Series Passive Probes and Accessories

Data Sheets

The N2870A Series passive probe family sets new standards in high performance probing of up to 1.5 GHz bandwidth. These general purpose probes and accessories offer high quality measurements at a very reasonable price.

Faithful reproduction of signals

The N2870A Series passive probes offer DC to 35 MHz, 200 MHz, 350 MHz, 500 MHz and 1.5 GHz bandwidths and various attenuation factors to address a wide range of measurement needs. For general purpose probing, you can use the N2873A 500 MHz model, which provides superior 10 MΩ input resistance, 9.5 pF of low input capacitance and low-inductance ground connection. This keeps probe loading low enough to achieve high signal integrity measurements. The 1.5 GHz passive probe offers even lower input capacitance for measuring faster edges more accurately, making it a low-cost alternative to an active probe.

All N2870A Series probes come with the probe ID readout feature, allowing the probe to be automatically recognized when connected to most Keysight Technologies, Inc. oscilloscopes.

  • Family of 7 mini passive probes spanning from 35 MHz to 1.5 GHz

  • Optional probe accessory kits
  • N2873A, 500 MHz, 10:1 probe ships with the 9000 Series Infiniium oscilloscope

Easy Access to Signals

The compact design with a 2.5 mm probe tip diameter provides better visibility to the circuit under test than conventional 5 mm or 3.5 mm probe tips. This makes it easier to probe today’s fine pitched space ICs and components. In addition, the replaceable probe tip is spring loaded, keeping it from slipping off the device you are probing. All N2870A Series probes come installed with one spring-loaded probe tip and four spare probe tips (2 spring-loaded tips, and 2 rigid tips).

To minimize the inductive effects that cause ringing of high speed signals, use the innovative ground blade or spring ground connection. Adhesive copper pads provided with the probe can be attached on top of an IC and connected to its ground pins to create a convenient ground plane for the probe to connect to. When used with the ground blade this method provides an ideal ground connection for probing signals with high frequency contents.

The IC caps fits over the probe tip, providing a convenient self-aligning connection to fine-pitch IC pins. Every N2870A Series probe comes with 5 different IC caps for IC lead pitches from 0.5 mm through 1.27 mm.
