Response = Vout/Vin
Notice how closely the output matches the input The flat response means the waveform on the scope screen will match
the waveform at the probe tip - across the entire 4 GHz bandwidth.
Small Size
Have you experienced problems with
large, clunky probes? If so, you
probably found your probe awkward
to hold and had difficulty connecting
to your signals. With the 1156/7/8A’s
small size 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 perform-
ance that is easy to use.
Faithful Reproduction of
Your Signal
Now you can accurately measure
your high-speed signals without
introducing errors from a probe that
has a resonant input impedance or
non-flat frequency response.
Resistance is placed as close as possi-
ble 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 on screen
matches the waveform at the probe
tip. No other probe currently on the
market offers a flat response for the
entire bandwidth of a 4 GHz probe!
With the wide dynamic range and
±15 V of offset, the probe can be used
in a wide variety of applications.
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
connection you use. Longer connections from your DUT produce lower
performance probing systems.
Agilent offers a variety of accessories optimized to give you the most
accurate reproduction of your signal. In addition, the performance of each
accessory is characterized for you. Now you can make informed decisions
and get the best measurement for your environment. Superior performance
combined with the knowledge to use it - that's how Agilent helps you do
your job better.
