Electrical Specifications
The electrical specifications in Table 2-3 apply to the devices in your calibration kit when
connected with a Keysight precision interface.
Certification
Keysight Technologies certifies that this product met its published specifications at the time of
shipment from the factory. Keysight further certifies that its calibration measurements are
traceable to the United States National Institute of Standards and Technology (NIST) to the
extent allowed by the Institute's calibration facility, and to the calibration facilities of other
International Standards Organization members. See “How Keysight Verifies the Devices in This
Kit” on page 4-2 for more information.

Sliding loads
a
a. Assuming proper usage, the specifications for the residual return loss after calibration for the
sliding load termination include: 
• the quality of the airline portions within the sliding load, combined with 
• the effective stability of the sliding element. 
Proper usage includes the following practices: 
• Connector mating surfaces are clean. 
• The changes in slide positioning are NOT done in equal steps since this results in very poor
calibration for some portions of the frequency range.

• The center conductor of test port connectors are nominally set back from the outer
conductor. 
Sliding loads are designed to allow the center conductor to be moved. The position of the
sliding load center conductor should be set by a reference block and not positioned flush
against the center conductor of the test port. 
