As the speeds in your design
increase, you may notice more
overshoot, ringing, and other per-
turbations when connecting an
oscilloscope probe. Probes form a
resonant circuit where they con-
nect to the device. If this reso-
nance is within the bandwidth of
the oscilloscope probe you are
using, it will be difficult to deter-
mine if the measured perturba-
tions are due to your circuit or
the probe.
These probes are compatible with
the AutoProbe interface, which
completely configures the oscillo-
scope for use with the probe.
Power for the active probe is sup-
plied by the oscilloscope.
Faithful Reproduction of Your Signal
Now you can accurately measure
your hi-speed signals without
introducing errors from a probe
that has a resonant input imped-
ance or non-flat frequency
response. With the 1156A/57A/58A
probes, a damping resistor is
placed as close as possible to the
point being probed, which keeps
the input impedance from res-
onating low, and it also allows a
flat frequency response across
the entire bandwidth of the probe.
Finally, there is a high-bandwidth
active probe where the waveform

a flat response for the entire
bandwidth of a 4 GHz probe!
Small Size
Have you experienced problems
with large, clunky probes? If so,
you probably found your probe
awkward to hold and had diffi-
culty connecting to your signals.
With the small size of the
1156A/57A/58A, you can handle
the probe expertly and gain
access to tight spaces. Plus, the
low mass makes the probe more
durable. Agilent makes your job
easier–giving you performance
that is easy to use.
Superior Accessories
Your device under test (DUT)
determines the type of probing
accessories you need. Of course,
there are electrical trade-offs
depending on the type of connec-
tion you use. Longer connections
from your DUT produce lower
performance probing systems.
Agilent offers a variety of acces-
sories optimized to give you the
most accurate reproduction of
your signal. In addition, the per-
formance of each accessory is
characterized for you. Now you
can make informed decisions and
get the best measurement for
your environment. Superior per-
formance combined with the
knowledge to use it–that’s how
Agilent helps you do your job better.
