• 10:1 attenuation

• Compatible with 5000, 6000, and

7000 Series 300-MHz - 1-GHz

oscilloscopes

Agilent 1144A active probe

The 1144A features 800-MHz

bandwidth, 1-MΩ input resistance,

2-pF input capacitance, 10:1

attenuation and ±40-Vdc + peak ac

maximum input voltage. An FET at the

input allows a high input resistance

and low input capacitance which

minimizes the loading of the circuit

under test. The output impedance

of the probe is 50-Ω which allows

the probe cable to be extended with

a 50-Ω coaxial cable. To use this

probe with 5000, 6000 or 7000 Series

oscilloscope, the 1142A power supply

is required. The 01144-61604 adapter

can be used with the power supply

to provide power for two channels of

active probing.
