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.
The Agilent 1144A can access power directly from the Agilent 54542,
54540, 54522, 54520, 54615B, 54616B and 54616C oscilloscopes. The
Agilent 54500 family of scopes provide power for two channels of
active probing. If four channels are needed, a special one-input,
two output adapter is available (Agilent 01144-61604). Two adapters
are needed for four channels of probing. The Agilent 54615B, 54616B
and 54616C provide power for one channel of active probing. If two
channels are needed the Agilent 01144-61604 can be used. If the
Agilent 1144A is used with any oscilloscope not listed above, then
the Agilent 1142A power supply is required. 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.
