6.4.1 Calibrating Measurements
To get the best and most accurate results, you have to calibrate the measurement. The
reflection and transmission measurement of the vector voltmeter each have their own
calibration procedures. To successfully calibrate the test setup, you have to connect
one or more calibration standards at the reference plane.
The process of calibration including the selection of a calibration kit works like that for
scalar or vector measurement. For more information see "
on page 178.
6.4.2 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 MEAS key.
► Press the "Reflection S11" softkey for reflection measurements on port 1 or the
"Transmission S21" softkey 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/DIST key.
The R&S ZVH opens an input field to set the center frequency.
► Enter a frequency of 1950 MHz.
