► Disconnect the "Open".
Next, the R&S FSH asks you to
connect a "Short" first to port 1,
then to port 2.
► Firmly connect the "Short" of the calibration standard to the ports.
► Press the "Continue" softkey to start calibration.
The R&S FSH calibrates the "Short".
► Disconnect the "Short".
Next, the R&S FSH asks you to
connect a "Load" (50
Ω termination)
first to port 1, then to port 2.
► Firmly connect the "Load" of the calibration standard to port 1.
► Press the "Continue" softkey to start calibration.
The R&S FSH calibrates the "Load".
► Disconnect the "Load".
Next, the R&S FSH asks you to set up
a "Through" connection from port 1 to
port 2.
► Firmly connect the "Through" connection to port 1 and port 2.
► Press the "Continue" softkey to start calibration.
The R&S FSH calibrates the "Through" connection.
After finishing the calibration routine, the R&S FSH shows that calibration is
finished for a short time (
). The status line now says (Cal) to indicate
successful calibration.
Selecting a calibration kit
To avoid phase errors, you have to define the characteristics of the calibration kit you'd
like to use and then select the calibration kit in use. The R&S FSH then corrects the
measurement results accordingly.
You can either use one of the calibration kits specifically designed for use with the
R&S FSH, e.g. the R&S FSH-Z28 and -Z29 calibration kits. Those provide an "Open",
"Short" and "Load" calibration standard in one piece. The characteristics of these
calibration kits are already part of the R&S FSH firmware.
You can create and edit calibration kits with the R&S FSH4View software and transfer
them to the R&S FSH via the USB or the LAN interface. The number of standards the
R&S FSH can store in its memory depends on the number of other data sets stored on
the R&S FSH.
