R&S FSH
Network Analyzer Mode
Performing Vector Measurements (R&S FSH-K42)

Calibrate the measurement for vector transmission measurements.
Vector measurements provide the full range of calibration methods for more accurate
results. Most full calibration methods require more than one calibration standard.
M
Press the "Calibration" softkey.
M
Select the appropriate menu item (calibration on two ports).
M
Perform calibration. For more information see "
M
Reconnect the DUT.
The R&S FSH shows the results of the vector transmission measurement on the
filter.
The R&S FSH shows the results of
the vector transmission
measurement and therefore the
filter characteristics.
You can change the measurement
configuration (e.g. the sweep time
or detector) or format (e.g. view
phase characteristics) without
affecting the accuracy of the
measurement.
For more information see "
Selecting the Measurement Format
Note that for calibration to remain valid, frequency parameters, bandwidth and
attenuation have to remain the same.
Depending on the calibration method, you can also select other result displays
(e.g. reflection measurements) without having to recalibrate the R&S FSH.
4.3.2 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.
M
Press the PRESET key.
M
Connect the DUT.
