Calibrate the R&S FSH for the return loss measurement.
The following example shows a scalar measurement of return loss. If the option R&S FSH-K2 is
installed, measurement must first be switched to scalar.
!
Press the MEAS key.
!
Press the MEAS MODE softkey.
!
Using the rotary knob or cursor keys, select SCALAR.
!
Confirm with the ENTER key or the MEAS MODE softkey.
!
In the main menu for the tracking generator, press
the REFLECT CAL softkey.
The R&S FSH prompts you to leave the measurement
port open.
!
Leave the test port of the R&S FSH-Z2 open.
!
Using the CONTINUE softkey, start the OPEN cali-
bration.
While calibration is in progress, the R&S FSH outputs
the message "Calibrating OPEN, please wait... ".
When OPEN calibration is over, the R&S FSH prompts you to perform SHORT calibration.
!
Connect a short to the test port of the R&S FSH-Z2.
!
Using CONTINUE, start the SHORT calibration.
While calibration is in progress, the R&S FSH outputs
the message "Calibrating SHORT, please wait... ".
When calibration is over, the R&S FSH outputs the
message "Reflect. calibrated" for 3 seconds.
Reflection is displayed in the upper right-hand corner
of the measurement diagram to indicate that the
R&S FSH is calibrated for reflection measurements.
!
Connect the DUT to the measurement port of the
R&S FSH-Z2 or R&S FSH-Z3.
The R&S FSH displays the return loss of the DUT.
