Low Cost, Great Performance

Talk about big performance in a

small package! The two-channel,

low-mass 1155A combines a

probe tip that weighs less than

1 gram with the superior per-

formance of an active probe. It’s

a powerful combination, ideal for

connecting to and testing fine-

pitch ICs, surface mount devices,

and dense circuit boards.

The 1155A probe joins high

bandwidth (750 MHz), low input

capacitance (2 pF), and high

resistance (1 MΩ). These features

are well suited for measuring fast

transition times on low voltage

signals that cannot tolerate the

circuit loading of passive probes.

A Wedge Probe Adapter, included

with the probe, allows for hands-

free probing of 0.5 mm ICs. The

Wedge provides accurate, me-

chanically non-invasive electrical

contact to the IC legs with little

chance of shorting. It’s easy to

insert and it stays put. For more

information on the Wedge, see

“Probing Accessories.” Leads are

available for connecting to a wide

variety of test points. See

“Ordering Information” for a

complete list.

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. A snap-

on BNC connector simplifies

attaching the probe to the scope.
