Despite every effort to minimize channel loss in a leading probe system like Agilent's InfiniiMax III, cables and probes inherently suffer losses. Sometimes, the loss can be considerable depending on the configuration. In other cases, it may be just enough to produce a variation in measurements and affect the consistency of the results. Furthermore, frequency and phase response characteristics can vary from probe to probe, requiring the characterization and consideration of each probe and cable to ensure the most accurate possible signal representation. Agilent's PrecisionProbe N2809A software helps engineers overcome these challenges by:
- Quickly correcting cable and channel insertion loss.
- Correcting probing problems such as phase linearity and magnitude flatness.
- Matching the frequency and phase response of each cable or probe in a circuit.
- Characterizing and compensating for losses in channel paths, such as switches, without the need for additional equipment.
- Probe impedance profile characterization.
PrecisionProbe is the first software integrated into a real-time oscilloscope that provides complete AC calibration for probes, not just DC calibration and skew correction. PrecisionProbe does not rely on externally generated S-parameter characterization files. These files, typically generated by other instruments such as time-domain reflectometers or vector network analyzers, can be time-consuming to set up and require extensive expertise to produce accurate and consistent results. PrecisionProbe, on the other hand, uses a built-in signal source in the oscilloscope to generate the files automatically. A software setup wizard guides engineers through the configuration and characterization of channel elements, such as probes, cables, and switches, using PrecisionProbe.
Addressing the challenges of multiport and multisite testing
Devices with multiple ports require fast and accurate multiport network analysis. Optimize your vector network analyzer configuration to minimize testing costs for these devices.
