Single-ended Active Probes
Agilent 1156A Single-ended Active Voltage
• 1.5 GHz probe bandwidth;
< 233 ps rise/fall time
• 100 kΩ, 0.8 pF non-resonant input
impedance
• Small size for easier probing
• Compatible with 5000, 6000 and
7000 Series (except for 6000 Series
100 MHz models)
The Agilent 1156A is a 1.5GHz
active probe for use with
Agilent InfiniiVision or Infiniium
oscilloscopes. Its high bandwidth
(1.5GHz), low input capacitance
(0.8pF) and high input resistance
(100 kΩ) input minimizes ultra low
loading of the DUT, making it ideal
for the companion for the 5000, 6000
or 7000 Series oscilloscopes. When
used with the 5000, 6000 or 7000
Series, the 1156A offers you a full
bandwidth of the scope to the probe
tip, giving you the accurate insight
into your hi-speed device.
Incorporating the most advanced
mechanical and electrical design
technologies, the 1156A provides
smaller, lighter and more rugged
probe tip that enables direct and
easy access to fine pitch ICs and
components. With the 1156A probe,
a damping resistor is placed as close
as possible to the point being probed,
which keeps the input impedance
from resonating low, and it also
allows a flat frequency resonance
across the entire bandwidth of the
probe. The 1156A is designed to
withstand 40-V peak AC input and
> –5-kV of ESD, so it will function
reliably in adverse condition.
