Rohde & Schwarz FSH20 - Performing Measurements

R&S FSH Network Analyzer Mode
Vector Voltmeter (R&S FSH-K45)
Operating Manual 1173.6275.12 - 30 211
6.6.2 Performing Measurements
With the vector voltmeter you can measure the reflection on port 1 and the
transmission in reverse direction.
The example included here is based on a transmission measurement of a two-port
filter. The filter works in the frequency from of 1920 MHz to 1980 MHz.
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 "Transmission Rev (Port 21)" menu item for transmission measurements in
reverse direction.
Define the frequency parameters
Before calibrating the measurement, you should define the frequency parameters to
avoid interpolation of the results.
► Press the FREQ key.
The R&S FSH opens an input field to set the center frequency.
► Enter a frequency of 1950 MHz.
6.6.2.1 Performing Transmission Measurements
Calibrate the measurement for transmission measurements.
► Press the "Calibration" softkey.
► Select the "Transmission Rev
(Port 21)" menu item.
► Perform calibration. For more
information see "Performing
Calibration".
► Reconnect the DUT.
The R&S FSH shows the
characteristics of the DUT
(magnitude and phase) as
numerical values.
You can change the measurement configuration (e.g. the sweep time) or format
(see "Selecting the Measurement Format") without affecting the accuracy of the
measurement.
