Faithful Reproduction of Signals
These probes offer bandwidths of 35 MHz, 200 MHz, 350 MHz, 500 MHz, 700 MHz,
and 1.5 GHz along with various attenuation ratios to address a wide range of mea-
surement needs. For general purpose probing, the N2873A’s superior 10 M
Ω
input
resistance, 9.5 pF of low input capacitance, and low inductance ground connection
keep probe loading low enough to achieve high signal integrity measurements. The
1.5 GHz passive probe offers an even lower input capacitance for measuring faster
edges more accurately, making it a good low-cost alternative to an active probe. All
of these probes are automatically recognized when connected to Keysight
InfiniiVision and Infiniium Series oscilloscopes.
Easy Access to Signals
The compact design along with a 2.5 mm probe tip diameter provide better visibility
of the circuit under test when compared to the conventional 5 mm or 3.5 mm
probes. This makes it easier to probe today’s fine pitched ICs and components. To
learn more about probe tips and accessories, refer to

Inspecting the Probe
• Inspect the shipping container for damage.
Keep the damaged shipping container or cushioning material until the contents
of the shipment have been checked for completeness and the probe has been
checked mechanically and electrically.
• Check the accessories.
If the contents are incomplete or damaged, notify your Keysight Technologies
Sales Office.
• Inspect the instrument.
If there is mechanical damage or defect, or if the probe does not operate
properly or pass performance verification tests, notify your Keysight
Technologies Sales Office.
If the shipping container is damaged, or the cushioning materials show signs of
stress, notify the carrier as well as your Keysight Technologies Sales Office. Keep
the shipping materials for the carrier’s inspection. The Keysight Technologies office
will arrange for repair or replacement at Keysight Technologies’ option without
waiting for claim settlement.
