Reliable Probing of
Low-Bandwidth Signals
The Agilent 1153A is a 1:1 FET
differential probe with 200 MHz
bandwidth and 3000:1 CMRR
(Common Mode Rejection Ratio)
at 1 MHz. Two attenuators, 10:1
and 100:1, expand the dynamic
range of the inputs up to + 30 V.
The probe has a high input resist-
ance of 1 MΩ and low input
capacitance of 7 pF to minimize
circuit loading.
Input coupling modes include dc,
dc with variable offset, and low-
frequency (LF) reject. The probe
also comes with an ac coupling
adapter for those cases where
signals in the presence of much
larger common-mode signals
to ±30 V with attenuation
frequency reject, ac coupling
the input dc voltage level pre-
vents the use of LF reject. LF
reject, like ac coupling, blocks
the dc component in a signal
without degrading low frequency
CMRR, which occurs when you
use blocking capacitors to accom-
plish ac coupling. The probe’s
dual-path amplifier design pro-
vides superior dc stability by
reducing the drift to less than
50 µV dc per degree Celsius.
The 1153A is designed for relia-
bility through use of over-voltage
protection circuitry, which
decreases the probe’s susceptibil-

ity to damage from electrostatic
discharge and other accidental
exposure to excessive voltage.
Special attention is paid to isolat-
ing critical parts from shock.
The probe is compatible with the
AutoProbe interface, which com-
pletely configures the Infiniium
scope for the probe. The probe
interface recognizes the probe
and automatically sets up the
proper power, coupling modes,
50 Ω impedance, and offset
range. A snap-on BNC connector
simplifies connecting the probe
to the scope.
