N2840/1/2/3A and N2853A User’s Guide
Introduction
Introduction
The N2840/1/2/3A and N2853A high-impedance passive probes and accessories
are a great choice for high quality at a very reasonable price. With the exception of
the N2840A, the probes include probe ID capability that allows most
oscilloscopes, such as Keysight’s InfiniiVision and Infiniium series, to detect the
probe’s impedance and attenuation ratio.
Oscilloscope Compatibility
To be compatible with the probes, the oscilloscope must have a 1 M
W
input
resistance shunted by 5 to 30 pF of input capacitance.
Handling the Probe
Handle the probe with care and refer to the safety notices in this manual. The
probe cable is a sensitive part of the probe, so use care not to damage the probe
through excessive bending or pulling. Avoid any mechanical shocks to the probe
to guarantee accurate performance and protection.
