General Information
Calibration Kit Overview
The shorts have a one-piece shorting plane that combines the inner and outer conductors.
The construction provides for extremely repeatable connections.
The opens have a low-dielectric collet depressor that is flush with the outer conductor.
Both the opens and shorts are constructed so that the pin depth can be controlled very
tightly, thereby minimizing phase errors. The lengths of the offsets in the opens and shorts
are designed so that the difference in phase of their reflection coefficients is approximately
180 degrees at all frequencies.
Broadband Load
The broadband load is a metrology-grade termination that has been optimized for
performance up to 18 GHz. The rugged internal structure provides for highly repeatable
connections. A distributed resistive element on sapphire provides excellent stability and
return loss. The broadband load is a valid substitute for a lowband load.
Sliding Loads
The sliding loads in this kit are designed to provide excellent performance from 3 GHz to
18 GHz. The inner and outer conductors of the airline portion are precision machined to
state-of-the-art tolerances. Although the sliding load has exceptional return loss, its
superior load stability qualifies it as a high-performance device.
The sliding load was designed with the ability to extend the inner conductor for connection
purposes and then pull it back to a preset pin depth. This feature is critical since it
minimizes the possibility of damage during the connection, while maintaining a minimum
pin depth to optimize performance.
Calibration Definitions
The calibration kit must be selected and the calibration definitions for the devices in the
kit installed in the network analyzer prior to performing a calibration.
The calibration definitions can be:
• resident within the analyzer
• downloaded from the Web at http:na.tm.agilent.com/pna/caldefs/stddefs.html.
• loaded from the provided disk (8510 series network analyzers only)
• manually entered from the front panel
Refer to your network analyzer user's guide or embedded Help for instructions on
manually entering calibration definitions, selecting the calibration kit, and performing a
calibration.
Equipment Required but Not Supplied
Connector cleaning supplies and various electrostatic discharge (ESD) protection devices
are not supplied with the calibration kit but are required to ensure successful operation of
the kit. Refer to
Table 6-1 on page 6-2
for ordering information.
