Making Measurements
Measuring S21 Forward Transmission using an Enhanced Response Calibration
Calibrating for Insertable Devices
When doing a through-standard calibration, normally the test ports
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 a user-defined calibration is
necessary, and information about other calibrations available for S
21
measurements. If you wish to perform an enhanced response calibration
on your instrument for an S
21
measurement, execute the following steps:
1. Press .
2. The instrument prompts you to connect four standards—open, short,
load, and through cable—as shown in the following graphic.
3. Press after connecting each standard.
