The 1145A is an Active Probe from Agilent. Use an electrical probe to test equipment and measure currents and voltages. Probes are an integral part of any electrical power testing toolbox to ensure accurate measurements, reliability, and safety. Probes can use pulse waveforms to test components without removing them from circuits with in-circuit capabilities. Choose the probe that complements your system.
Additional Features:
2 channels per assembly
dc to 750-MHz probe bandwidth
1-MΩ input resistance
1.6-pF input capacitance
10X attenuation
Signal-ground pairs with 100-mil spacing
50-mil SOIC and QUAD packages
25-mil square pin socket on basic tip mates with most industry standard IC package adapters
25-mil JEDEC, 0.5-mm EIAJ, 0.65-mm EIAJ packages
Powered directly by Agilent Technologies 54520A, 54522A, 54540A, and 54542A oscilloscopes
Compatible with oscilloscope’s 50 ohm BNC input. Use the Agilent 1142A external power supply with any other instrument with 50 Ω inputs.
Surface-mount packages on PC boards have become the norm rather than the exception. In the future, nearly 100 percent of both sides of a typical PC board will use SMDs. As a result, bulky probes may become useless as package sizes get smaller and smaller. The 2-channel Agilent 1145A provides easy and reliable connection to SMDs on PC boards and backplanes, while delivering active probe performance down to the tip. Its unique design also presents a powerful combination of industry-standard compatibility and superior reliability. The probe’s basic contact is a standard 25-mil square pin socket that houses only passive circuitry. The active circuitry is contained in a plastic pod 13 inches from the tip. This design ensures a small, lightweight, and rugged tip. The electrical performance of the 1145A is unmatched by any off-the-shelf probe designed for SMD probing. The probe combines high bandwidth, high input resistance, and low input capacitance. This combination is superior to that of passive divider probes that have higher input capacitance because it provides minimal circuit loading at high and low frequencies (see the Impedance vs. Frequency graph). As signal speeds increase, passive divider probes don’t deliver the performance needed. This lower performance can result in waveshapes that do not represent the actual signal. The 1145A used with an 54542A scope, for example, introduces the equivalent of only ½ of a typical CMOS gate load (approximately 3.0 pF per gate) to a CMOS circuit. Other SMD probes used with comparable scopes can introduce 1½ or more gate loads to the circuit under test. A versatile set of accessories lets you probe most any SMD package. The standard socket also makes the 1145A compatible with probing adapters from other vendors for faultfree probing of SMDs including 5-mil JEDEC, 0.5-mm EIAJ, 0.65-mm EIAJ packages.
