AGILENT Technologies has introduced a 1.5 GHz differential probe that offers high performance at a low price.
When the Agilent InfiniiMax 1130A differential probe is paired with Agilent's Infiniium mixed signal (MSO) and digital signal oscilloscopes (DSO), the system delivers great accuracy and probing connectivity to R&D engineers in the computer, communications and semiconductor industries for validating and verifying the performance of new high-speed digital product designs.
Agilent claims that as embedded design speeds increase, oscilloscope users are migrating from 500 MHz to 1GHz oscilloscopes but continue to use their traditional passive probes that limit system bandwidth to 600MHz. This presents significant loading to the circuit under test. With the Agilent differential probe, users can realise the full system bandwidth of their 1GHz oscilloscope. The Agilent InfiniiMax 1130A 1.5GHz differential probe rounds out Agilent's InfiniiMax 1130-series single-ended/differential probe system, giving designers the flexibility to choose the probe that matches their application need.
The new probe helps engineers maximise the capabilities of the Agilent Infiniium 54830-series of MSOs and DSOs. For example, Agilent Infiniium MSOs enable engineers to easily view up to 20 time-aligned (4 scope + 16 logic timing) signals on one instrument, and offer triggering capabilities that help speed testing and debugging of new digital products.
Traditional probes are designed to make only single-ended or differential measurements, but not both. The flexible architecture of the Agilent 1130A differential probe enables engineers to make either single-ended or differential measurements from a single probe amplifier. Because the majority of designers make measurements on both types of signals, the InfiniiMax probe design can significantly reduce costs.
In addition, the new probe offers exclusive controlled transmission-line probe heads. These provide a flat frequency response over the entire bandwidth specification and eliminate the distortion and loading that affects probes with in-band resonance. The probes enable designers to achieve 1GHz system bandwidth when used in conjunction with the Agilent Infiniium 54830-series of 1GHz MSOs and DSOs, even when manually browsing with the probe.
The probe has resistor tip technology, which compensates for the inductance and capacitance associated with the probe tips to prevent distortion of the measured signals.
An extensive line of optional probe heads and accessories are available. These provide significant connectivity to full bandwidth even in the most difficult-to-reach situations, such as probing between memory modules on server motherboards.
Finally, the new probe features variable span between the signal tips, enabling engineers to adapt the probes to the design. When a small probe size is not needed, an adapter is available that makes long-term browsing more comfortable. Solder-in sockets are available for signals that need frequent measurement. The differential probe tips can flex to support various probing angles and target system characteristics for z-axis compliance. In addition, replaceable browser tips improve the usability and versatility of Agilent InfiniiMax probes.
