General Purpose Differential Active Probes - 1153A/41A Low-noise

Differential Probes

The 1141A is a 1x FET differential probe with

200-MHz bandwidth and a 3000:1 CMRR.

The probe has a high-input resistance and

low-input capacitance of 7 pF to minimize

circuit loading. The 1141A must be used with

1142A probe control and power module,

which controls input coupling modes dc,

dc with variable offset, and dc reject. Two

attenuators, 10x and 100x are provided to

expand the linear differential input range to

±30 V. This probe works with any 50-Ω input

oscilloscope.

The 1153A is the same 1:1 differential probe

with 200 MHz as the 1141A except that it

is compatible with the AutoProbe interface,

which completely configures the Infiniium

scope for the probe. The probe interface

recognizes the probe and automatically

sets up the proper power, coupling mode,

50 Ω impedance and offset range. The

1142A probe power supply is unnecessary

with the 1153A. The probe works with any

Infiniium oscilloscope with AutoProbe I

interface.
