Overview of Characteristics
This chapter contains analyzer performance data for SRL and fault location
measurements. For complete specification and characteristic information for your
analyzer, see your analyzer's User's Guide.
Frequency Range Considerations
The higher frequency span available on the Agilent Technologies E5061A/E5062A
can provide greater resolution when making fault location measurements. See the
discussion in
“Fault Location Distance Range and Resolution” on page 96.
However, when the analyzer has chosen a large frequency span (based on the
user-defined start and stop distances), the performance of the system at high
frequencies may become important.
Many coaxial cables perform poorly (or not at all) above 1500 MHz. If the cable or
system you are measuring does not perform well at high frequencies, change the
fault location frequency mode to band pass. Band pass mode may be used to limit
the frequency range the analyzer will use when making fault location measurements.
Phase Considerations
In addition to using the connector capacitance and connector length functions to
improve the connector model, you can use the electrical length and port extension
features. Electrical length and port extension provide the same function as connector
length, but these settings are entered in units of seconds, rather than length.
SRL data can also be observed in Smith chart format. The Smith chart can be used
to verify the connector model for your SRL measurements.
See “Determine the Connector Model” on page 65 for more information.
