Making Measurements
Measuring Transmission Response
NOTE
By convention, cal kit labels in the analyzer indicate the sex of the port
with which they are used. For example, the default cal kit for the
analyzer is type-N female because the front panel RF ports are female
(the calibration standards, in turn, have male connectors).
Calibrating for Insertable Devices
When measuring a through-standard during calibration, the test ports
normally mate directly together. For example, two cables with the
appropriate connectors can be connected directly without a
through-adapter, resulting in a zero-length through-standard. An
insertable device is a device that can be inserted in place of a zero-length
through-standard. It has the same type of connector on each port, but
with a different sex, or the same type of sexless connector on each port
(APC-7, for example).
Chapter 6 provides detail about when this calibration is necessary, and
information about other calibrations available for transmission
measurements. If you wish to perform an enhanced response calibration
on your insertable device, perform the following steps:
NOTE If you are going to be using calibration standards other than the default
(female type-N), you must select the connector type by pressing
and then selecting the appropriate type.
1. Press .
2. The instrument prompts you to connect four standards—open, short,
load, and through cable—as shown in the following graphic.
