Agilent Probe Control and Power Module Model: 1142A

**This unit has been tested to specifications. Has slight cosmetic blemishes from normal use. See photos for further details. 

Includes:

• 1144A 800 MHz Active Single-ended Probe.
• 1142A Probe Control and Power Module

 The Keysight / Agilent / HP 1142A Probe Control and Power Module can power and control the 1141A Active Differential Probe, 1144A 800 MHz Active Single-ended Probe and the 1145A 750 MHz Active Single-ended Probe. If the instrument does not have an internal 50-ohm termination, an external termination adapter can be used with a high-impedance output. 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 ±30V. This probe works with any 50 input oscilloscope including 54640-Series.

• Can power and control the 1141A, 1144A, and the 1145A.
• If the instrument does not have an internal 50-ohm termination, an external termination adapter can be used with a high-impedance output.

The Agilent 1144A active probe provides an excellent combination of high bandwidth, high input resistance, and low input capacitance. This combination is superior to that of passive divider probes because it provides minimal circuit loading at high and low frequencies. As signal speeds increase, passive divider probes may not deliver the performance needed. This can result in waveshapes that do not represent the actual signal. To help you minimize circuit loading, the Agilent 1144A boasts a 800 MHz bandwidth, 1 M Ohm input resistance, and 2 pF input capacitance. It can be connected to any instrument with 50 Ohm inputs. An external 50 Ohm termination can also be used with high impedance inputs.

For use with 6000 Series 300 MHz – 1 GHz, 54641A/D and 54642A/D oscilloscopes the Agilent 01144-61604 adapter can be used with this power supply to provide power for two channels of active probing. Versatile accessories allow for easy connection to your device under test. For example, the dual lead adapter combines with the two mini-pincher tips to provide a solid connection to 0.050 inch pitch surface mount devices for hands-off probing. Also, the ground bayonet has a short ground lead to minimize measurement errors such as ringing, caused by parasitic inductances. For hands-off probing of SMT components with 0.5 mm (0.020 inch) to 0.8 mm (0.032 inch) pitch, an additional accessory is available: the Agilent 10075A 0.5 mm IC Clips Accessory Kit.
