R&S FSH Network Analyzer Mode
Performing Vector Measurements (R&S FSH-K42)
Operating Manual 1173.6275.12 - 30 195
6.4.2 Measuring the Reflection
The example included here is based on a reflection measurement of the two-port filter
that was also used for the transmission measurement.
You can skip the preset, vector measurement selection and frequency settings if you
have already set up the R&S FSH for the measurement. You can also skip the
calibration, if you have performed the appropriate calibration already.
Preset the R&S FSH
Before starting the measurement procedure, preset the R&S FSH to restore the default
configuration and connect the filter between the measurement ports.
► Press the PRESET key.
► Connect the DUT.
Start vector measurements.
► Press the MEAS key.
► Press the "Meas Mode" softkey.
► Select the "Vector" menu item.
Select the type of reflection measurement
► Press the "Result Display" softkey.
► Select the "Reflection Port 1" menu item for reflection measurements on port 1 or
the "Reflection Port 2" menu item for reflection measurements on port 2.
► Select the "Reflection on Port 1 and Port 2" menu item for simulatenous display of
the reflection on both ports.
For more information see "Performing Scalar Measurements" on page 187.
Simultaneous display of several results
You can also display two results simultaneously in a single diagram. In that case, the
R&S FSH shows two traces with a different color in the result display.
See “Measuring the Transmission” for more information.
